FluentFTP A connection to a single FTP server. Interacts with any FTP/FTPS server and provides a high-level and low-level API to work with files and folders. Debugging problems with FTP is much easier when you enable logging. See the FAQ on our Github project page for more info. Automatic FTP and FTPS connection negotiation. This method tries every possible combination of the FTP connection properties, and returns the list of successful connection profiles. You can configure it to stop after finding the first successful profile, or to collect all successful profiles. You can then generate code for the profile using the FtpProfile.ToCode method. If no successful profiles are found, a blank list is returned. Find all successful profiles (false) or stop after finding the first successful profile (true)? Connect to the given server profile. Connect to the given server profile. Load the given connection profile and configure the FTP client instance accordingly. Connection profile. Not modified. Automatic FTP and FTPS connection negotiation. This method tries every possible combination of the FTP connection properties, and connects to the first successful profile. Returns the FtpProfile if the connection succeeded, or null if it failed. Automatic FTP and FTPS connection negotiation.

Enhanced-passive mode is tried once, and if not supported, is not tried again. Used to improve performance of GetFileSize. SIZE command is tried, and if the server cannot send it in ASCII mode, we switch to binary each time you call GetFileSize. However most servers will support ASCII, so we can get the file size without switching to binary, improving performance. Used to improve performance of GetListing. You can set this to true by setting the RecursiveList property. Used to automatically dispose cloned connections after FXP transfer has ended. These flags must be reset every time we connect, to allow for users to connect to different FTP servers with the same client object. These flags must be copied when we quickly clone the connection. Used for internally synchronizing access to this object from multiple threads For usage by FTP proxies only A list of asynchronous methods that are in progress Control connection socket stream Gets a value indicating if this object has already been disposed. Gets the base stream for talking to the server via the control connection. Flags specifying which versions of the internet protocol to support when making a connection. All addresses returned during name resolution are tried until a successful connection is made. You can fine tune which versions of the internet protocol to use by adding or removing flags here. I.e., setting this property to FtpIpVersion.IPv4 will cause the connection process to ignore IPv6 addresses. The default value is ANY version. Gets or sets the length of time in milliseconds that must pass since the last socket activity before calling on the socket to test for connectivity. Setting this interval too low will have a negative impact on performance. Setting this interval to 0 disables Polling all together. The default value is 15 seconds. Gets or sets a value indicating whether a test should be performed to see if there is stale (unrequested data) sitting on the socket. In some cases the control connection may time out but before the server closes the connection it might send a 4xx response that was unexpected and can cause synchronization errors with transactions. To avoid this problem the method checks to see if there is any data available on the socket before executing a command. On Azure hosting platforms this check can cause an exception to be thrown. In order to work around the exception you can set this property to false which will skip the test entirely however doing so eliminates the best effort attempt of detecting such scenarios. See this thread for more details about the Azure problem: https://netftp.codeplex.com/discussions/535879 Gets a value indicating if the connection is alive When this value is set to true (default) the control connection is cloned and a new connection the server is established for the data channel operation. This is a thread safe approach to make asynchronous operations on a single control connection transparent to the developer. Gets or sets the length of time in milliseconds after last command (NOOP or other) that a NOOP command is sent by . This is called during downloading/uploading if is false. Setting this interval to 0 disables all together. The default value is 0 (disabled). When this value is set to true (default) the control connection will set which features are available by executing the FEAT command when the connect method is called. Gets a value indicating if this control connection is a clone. This property is used with data streams to determine if the connection should be closed when the stream is closed. Servers typically only allow 1 data connection per control connection. If you try to open multiple data connections this object will be cloned for 2 or more resulting in N new connections to the server. Gets or sets the text encoding being used when talking with the server. The default value is however upon connection, the client checks for UTF8 support and if it's there this property is switched over to . Manually setting this value overrides automatic detection based on the FEAT list; if you change this value it's always used regardless of what the server advertises, if anything. The server to connect to The port to connect to. If this value is set to 0 (Default) the port used will be determined by the type of SSL used or if no SSL is to be used it will automatically connect to port 21. Credentials used for authentication Gets or sets a value that controls the maximum depth of recursion that will follow symbolic links before giving up. You can also specify the value to be used as one of the overloaded parameters to the method. The default value is 20. Specifying -1 here means indefinitely try to resolve a link. This is not recommended for obvious reasons (stack overflow). Client certificates to be used in SSL authentication process Delegate used for resolving local address, used for active data connections This can be used in case you're behind a router, but port forwarding is configured to forward the ports from your router to your internal IP. In that case, we need to send the router's IP instead of our internal IP. See example: FtpClient.GetPublicIP -> This uses Ipify api to find external IP Ports used for Active Data Connection. Useful when your FTP server has certain ports that are blocked or used for other purposes. Ports blocked for Passive Data Connection (PASV and EPSV). Useful when your FTP server has certain ports that are blocked or used for other purposes. Maximum number of passive connections made in order to find a working port for Passive Data Connection (PASV and EPSV). Only used if PassiveBlockedPorts is non-null. Data connection type, default is AutoPassive which tries a connection with EPSV first and if it fails then tries PASV before giving up. If you know exactly which kind of connection you need you can slightly increase performance by defining a specific type of passive or active data connection here. Disconnect from the server without sending QUIT. This helps work around IOExceptions caused by buggy connection resets when closing the control connection. Gets or sets the length of time in milliseconds to wait for a connection attempt to succeed before giving up. Default is 15000 (15 seconds). Gets or sets the length of time wait in milliseconds for data to be read from the underlying stream. The default value is 15000 (15 seconds). Gets or sets the length of time in milliseconds for a data connection to be established before giving up. Default is 15000 (15 seconds). Gets or sets the length of time in milliseconds the data channel should wait for the server to send data. Default value is 15000 (15 seconds). Gets or sets a value indicating if should be set on the underlying stream's socket. If the connection is alive, the option is adjusted in real-time. The value is stored and the KeepAlive option is set accordingly upon any new connections. The value set here is also applied to all future data streams. It has no affect on cloned control connections or data connections already in progress. The default value is false. Gets the server capabilities represented by an array of capability flags Get the hash types supported by the server, if any. This is a recent extension to the protocol that is not fully standardized and is not guaranteed to work. See here for more details: http://tools.ietf.org/html/draft-bryan-ftpext-hash-02 Type of SSL to use, or none. Default is none. Explicit is TLS, Implicit is SSL. Indicates if data channel transfers should be encrypted. Only valid if property is not equal to . Encryption protocols to use. Only valid if EncryptionMode property is not equal to . Default value is .NET Framework defaults from the class. Whether to use SSL Buffering to speed up data transfer during FTP operations. SSL Buffering is always disabled on .NET 5.0 due to platform issues (see issue 682 in FluentFTP issue tracker). Checks if FTPS/SSL encryption is currently active. Useful to see if your server supports FTPS, when using FtpEncryptionMode.Auto. Event is fired to validate SSL certificates. If this event is not handled and there are errors validating the certificate the connection will be aborted. Not fired if ValidateAnyCertificate is set to true. Accept any SSL certificate received from the server and skip performing the validation using the ValidateCertificate callback. Useful for Powershell users. Indicates if the certificate revocation list is checked during authentication. Useful when you need to maintain the certificate chain validation, but skip the certificate revocation check. WARNING: Enabling this can cause memory leaks in some conditions (see issue #710 for details). Gets the type of system/server that we're connected to. Typically begins with "WINDOWS" or "UNIX". Gets the type of the FTP server software that we're connected to. Gets the type of the FTP server handler. This is automatically set based on the detected FTP server, if it is detected.

Gets the connection type Gets the last reply received from the server Controls if the file listings are downloaded in Binary or ASCII mode. File listing parser to be used. Automatically calculated based on the type of the server, unless changed. Culture used to parse file listings Custom file listing parser to be used. Callback format to implement your custom FTP listing line parser. The line from the listing The server capabilities The FTP client Return an FtpListItem object if the line can be parsed, else return null Detect if your FTP server supports the recursive LIST command (LIST -R). If you know for sure that this is supported, return true here. The timezone of the FTP server. If the server is in Tokyo with UTC+9 then set this to 9. If the server returns timestamps in UTC then keep this 0. The timezone of your machine. If your machine is in Tokyo with UTC+9 then set this to 9. If your machine is synchronized with UTC then keep this 0. Server timestamps are converted into the given timezone. ServerTime will return the original timestamp. LocalTime will convert the timestamp into your local machine's timezone. UTC will convert the timestamp into UTC format (GMT+0). You need to set TimeZone and LocalTimeZone (.NET core only) for these to work. If true, increases performance of GetListing by reading multiple lines of the file listing at once. If false then GetListing will read file listings line-by-line. If GetListing is having issues with your server, set it to false. The number of bytes read is based upon . Bytes to read during GetListing. Only honored if is true. Gets or sets the number of bytes transferred in a single chunk (a single FTP command). Used by / and / to transfer large files in multiple chunks. Gets or sets the size of the file buffer when reading and writing files on the local file system. Used by / and / and all the other file and directory transfer methods. Files within this size are read and written in a single call to the disk, thereby greatly increasing transfer performance. Measured in bytes. Reduce this if you notice large memory consumption by FluentFTP. Set this to 0 to disable quick transfer. Gets or sets the retry attempts allowed when a verification failure occurs during download or upload. This value must be set to 1 or more. Rate limit for uploads in kbyte/s. Set this to 0 for unlimited speed. Honored by high-level API such as Upload(), Download(), UploadFile(), DownloadFile().. Rate limit for downloads in kbytes/s. Set this to 0 for unlimited speed. Honored by high-level API such as Upload(), Download(), UploadFile(), DownloadFile().. Controls if zero-byte files should be downloaded or skipped. If false, then no file is created/overwritten into the filesystem. Controls if the high-level API uploads files in Binary or ASCII mode. Controls if the high-level API downloads files in Binary or ASCII mode. Controls if the UploadDirectory API deletes the excluded files when uploading in Mirror mode. If true, then any files that are excluded will be deleted from the FTP server if they are excluded from the local system. This is done to keep the server in sync with the local system. But if it is false, the excluded files are not touched on the server, and simply ignored. Controls if the DownloadDirectory API deletes the excluded files when downloading in Mirror mode. If true, then any files that are excluded will be deleted from the local filesystem if they are excluded from the FTP server. This is done to keep the local filesystem in sync with the FTP server. But if it is false, the excluded files are not touched on the local filesystem, and simply ignored. Controls if the FXP server-to-server file transfer API uses Binary or ASCII mode. Controls how often the progress reports are sent during an FXP file transfer. The default value is 1000 (1 second). Controls if the HOST command is sent immediately after the handshake. Useful when you are using shared hosting and you need to inform the FTP server which domain you want to connect to. Controls which domain is sent with the HOST command. If this is null, then the Host parameter of the FTP client is sent. The local socket will be bound to the given local IP/interface. This is useful if you have several usable public IP addresses and want to use a particular one. Returns the local end point of the FTP socket, if it is available. Returns the remote end point of the FTP socket, if it is available. Connects to the specified URI. If the path specified by the URI ends with a / then the working directory is changed to the path specified.

Supports the MLST command Supports the SIZE command Supports the MDTM command Supports download/upload stream resumes Supports UTF8 PRET Command used in distributed ftp server software DrFTPD Server supports the MFMT command for setting the modified date of an object on the server Server supports the MFCT command for setting the created date of an object on the server Server supports the MFF command for setting certain facts about file system objects. It typically allows you to modify the last modification time, creation time, UNIX group/owner/mode of a file. Server supports the STAT command Support for the HASH command Support for the MD5 command Support for the XMD5 command Support for the XCRC command Support for the XSHA1 command Support for the XSHA256 command Support for the XSHA512 command Support for the EPSV file-transfer command Support for the CPSV command Support for the NOOP command Support for the CLNT command Support for the SSCN command Support for the SITE MKDIR (make directory) server-specific command for ProFTPd Support for the SITE RMDIR (remove directory) server-specific command for ProFTPd Support for the SITE UTIME server-specific command for ProFTPd Support for the SITE SYMLINK server-specific command for ProFTPd Support for the AVBL (get available space) server-specific command for Serv-U Support for the THMB (get image thumbnail) server-specific command for Serv-U Support for the RMDA (remove directory) server-specific command for Serv-U Support for the DSIZ (get directory size) server-specific command for Serv-U Support for the HOST (get host) server-specific command for Serv-U Support for the CCC (Clear Command Channel) command, which makes a secure FTP channel revert back to plain text. Support for the MODE Z (compression enabled) command, which says that the server supports ZLIB compression for all transfers Support for the LANG (language negotiation) command. Support for the MMD5 (multiple MD5 hash) command. Flags that control how file comparison is performed. If you are unsure what to use, set it to Auto. Compares the file size and the checksum of the file (using the first supported hash algorithm). The local and remote file sizes and checksums should exactly match for the file to be considered equal. Compares the file size. Both file sizes should exactly match for the file to be considered equal. Compares the date modified of the file. Both dates should exactly match for the file to be considered equal. Compares the checksum or hash of the file using the first supported hash algorithm. Both checksums should exactly match for the file to be considered equal. The result of a file comparison operation. Success. Local and remote files are exactly equal. Failure. Local and remote files do not match. Failure. Either the local or remote file does not exist. Failure. Checksum verification is enabled and your server does not support any hash algorithm. Data connection type This type of data connection attempts to use the EPSV command and if the server does not support EPSV it falls back to the PASV command before giving up unless you are connected via IPv6 in which case the PASV command is not supported. Passive data connection. EPSV is a better option if it's supported. Passive connections connect to the IP address dictated by the server which may or may not be accessible by the client for example a server behind a NAT device may give an IP address on its local network that is inaccessible to the client. Please note that IPv6 does not support this type data connection. If you ask for PASV and are connected via IPv6 EPSV will automatically be used in its place. Same as PASV except the host supplied by the server is ignored and the data connection is made to the same address that the control connection is connected to. This is useful in scenarios where the server supplies a private/non-routable network address in the PASV response. It's functionally identical to EPSV except some servers may not implement the EPSV command. Please note that IPv6 does not support this type data connection. If you ask for PASV and are connected via IPv6 EPSV will automatically be used in its place. Extended passive data connection, recommended. Works the same as a PASV connection except the server does not dictate an IP address to connect to, instead the passive connection goes to the same address used in the control connection. This type of data connection supports IPv4 and IPv6. This type of data connection attempts to use the EPRT command and if the server does not support EPRT it falls back to the PORT command before giving up unless you are connected via IPv6 in which case the PORT command is not supported. Active data connection, not recommended unless you have a specific reason for using this type. Creates a listening socket on the client which requires firewall exceptions on the client system as well as client network when connecting to a server outside of the client's network. In addition the IP address of the interface used to connect to the server is the address the server is told to connect to which, if behind a NAT device, may be inaccessible to the server. This type of data connection is not supported by IPv6. If you specify PORT and are connected via IPv6 EPRT will automatically be used instead. Extended active data connection, not recommended unless you have a specific reason for using this type. Creates a listening socket on the client which requires firewall exceptions on the client as well as client network when connecting to a server outside of the client's network. The server connects to the IP address it sees the client coming from. This type of data connection supports IPv4 and IPv6. Type of data transfer to do ASCII transfer Binary transfer Controls how timestamps returned by the server are converted. Returns the server timestamps in Server Time. No timezone conversion is performed. Returns the server timestamps in Local Time. Ensure that the TimeZone property is correctly set to the server's timezone. If you are on .NET Core/.NET Standard, you need to set the LocalTimeZone property for this to work. Returns the server timestamps in UTC (Coordinated Universal Time). Ensure that the TimeZone property is correctly set to the server's timezone. Defines the type of encryption to use Plain text. FTPS encryption is used from the start of the connection, port 990. Connection starts in plain text and FTPS encryption is enabled with the AUTH command immediately after the server greeting. FTPS encryption is used if supported by the server, otherwise it falls back to plaintext FTP communication. Defines how multi-file processes should handle a processing error. & Cannot Be Combined No action is taken upon errors. The method absorbs the error and continues. If any files have completed successfully (or failed after a partial download/upload) then should be deleted. This will simulate an all-or-nothing transaction downloading or uploading multiple files. If this option is not combined with or then the method will continue to process all items whether if they are successful or not and then delete everything if a failure was encountered at any point. The method should stop processing any additional files and immediately return upon encountering an error. Cannot be combined with The method should stop processing any additional files and immediately throw the current error. Cannot be combined with Type of file system of object The default subtype. A sub directory within the listed directory. (Only set when machine listing is available and type is 'dir') The self directory. (Only set when machine listing is available and type is 'cdir') The parent directory. (Only set when machine listing is available and type is 'pdir') Type of file system of object A file A directory A symbolic link Determines how we handle downloading and uploading folders Dangerous but useful method! Uploads/downloads all the missing files to update the server/local filesystem. Deletes the extra files to ensure that the target is an exact mirror of the source. Safe method! Uploads/downloads all the missing files to update the server/local filesystem. Different types of hashing algorithms for computing checksums. HASH command is not supported SHA-1 SHA-256 SHA-512 MD5 CRC IP Versions to allow when connecting to a server. Internet Protocol Version 4 Internet Protocol Version 6 Allow any supported version Flags that can control how a file listing is performed. If you are unsure what to use, set it to Auto. Tries machine listings (MDTM command) if supported, and if not then falls back to OS-specific listings (LIST command) Load the modify date using MDTM when it could not be parsed from the server listing. This only pertains to servers that do not implement the MLSD command. Load the file size using the SIZE command when it could not be parsed from the server listing. This only pertains to servers that do not support the MLSD command. Combines the Modify and Size flags Show hidden/dot files. This only pertains to servers that do not support the MLSD command. This option makes use the non standard -a parameter to LIST to tell the server to show hidden files. Since it's a non-standard option it may not always work. MLSD listings have no such option and whether or not a hidden file is shown is at the discretion of the server. Force the use of OS-specific listings (LIST command) even if machine listings (MLSD command) are supported by the server Use the NLST command instead of LIST for a reliable file listing Force the use of the NLST command (the slowest mode) even if machine listings and OS-specific listings are supported by the server Try to dereference symbolic links, and stored the linked file/directory in FtpListItem.LinkObject Sets the ForceList flag and uses `LS' instead of `LIST' as the command for getting a directory listing. This option overrides ForceNameList and ignores the AllFiles flag. Gets files within subdirectories as well. Adds the -r option to the LIST command. Some servers may not support this feature. Do not retrieve path when no path is supplied to GetListing(), instead just execute LIST with no path argument. Include two extra items into the listing, for the current directory (".") and the parent directory (".."). Meaningless unless you want these two items for some reason. Force the use of STAT command for getting file listings Determines how we handle partially downloaded files Restart the download of a file if it is partially downloaded. Overwrites the file if it exists on disk. Resume the download of a file if it is partially downloaded. Appends to the file if it exists, by checking the length and adding the missing data. If the file doesn't exist on disk, a new file is created. Blindly skip downloading the file if it exists on disk, without any more checks. This is only included to be compatible with legacy behaviour. Defines the operating system of the FTP server.

Machine listing parser, works on any FTP server supporting the MLST/MLSD commands. File listing parser for Windows/IIS. File listing parser for Unix. Alternate parser for Unix. Use this if the default one does not work. File listing parser for Vax/VMS/OpenVMS. File listing parser for IBM OS400. File listing parser for Tandem/Nonstop Guardian OS. Types of file permissions No access Executable Writable Readable This enum is obsolete. Please use FtpRemoteExists instead. Defines the behavior for uploading/downloading files that already exist Do not check if the file exists. A bit faster than the other options. Only use this if you are SURE that the file does not exist on the server. Otherwise it can cause the UploadFile method to hang due to filesize mismatch. Skip the file if it exists, without any more checks. Overwrite the file if it exists. Append to the file if it exists, by checking the length and adding the missing data. Append to the file, but don't check if it exists and add missing data. This might be required if you don't have permissions on the server to list files in the folder. Only use this if you are SURE that the file does not exist on the server otherwise it can cause the UploadFile method to hang due to filesize mismatch. The type of response the server responded with No response Success Success Success Temporary failure Permanent failure Determines how SSL Buffering is handled Enables buffering in all cases except when using FTP proxies.

Depending on the framework version this is translated to an equivalent logging level in System.Diagnostices (if available) Used for logging Debug or Verbose level messages Used for logging Informational messages Used for logging non-fatal or ignorable error messages Used for logging Error messages that may need investigation Defines if additional verification and actions upon failure that should be performed when uploading/downloading files using the high-level APIs. Ignored if the FTP server does not support any hashing algorithms. No verification of the file is performed The checksum of the file is verified, if supported by the server. If the checksum comparison fails then we retry the download/upload a specified amount of times before giving up. (See ) The checksum of the file is verified, if supported by the server. If the checksum comparison fails then the failed file will be deleted. If combined with , then the deletion will occur if it fails upon the final retry. The checksum of the file is verified, if supported by the server. If the checksum comparison fails then an exception will be thrown. If combined with , then the throw will occur upon the failure of the final retry, and/or if combined with the method will throw after the deletion is processed. The checksum of the file is verified, if supported by the server. If the checksum comparison fails then the method returns false and no other action is taken.
