-For performance reasons resuming file transfer is supported only for files larger then a given threshold. By default the threshold is 100 kB. You can change it, enable resume for all files (not recommended) or disable it altogether.+&toc_title_page_sections
 +===== [[temporary]] Transfer Resume / Transfer to Temporary Filename =====
 +WinSCP is able to [[resume#automatic|transfer files to temporary filename]] first, renaming it to the target name only once the transfer successfully finishes. This allows for [[resume#automatic|automatic transfer resume]]; as well as preserving the existing target file for duration of the transfer (what is particularly useful when updating frequently accessed files on web sites).
 +
 +Transfer to temporary filename is supported with [[sftp|SFTP protocol]] only and only for [[transfer_mode|binary transfers]]. However with other protocols you can resume transfers also [[resume#manual|manually]]. Though the option still has some effect with the FTP protocol, it controls whether a file transfer is automatically resumed, after a connection is restored, when it breaks in a middle of a file transfer, or if the transfer restarts from the beginning.
 +
 +In [[scripting]],  use ''-resumesupport'' switch of [[scripting#commands|file transfer commands]]. In .NET assembly, use ''[[library_transferoptions#resumesupport|TransferOptions.ResumeSupport]]'' property.
 +
 +===== [[reconnect]] Automatic Reconnect =====
 +Use the //Automatically reconnect session, if it breaks during transfer// checkbox to enable reconnection of the session (and resuming transfer) when it breaks while transferring files. This is supported with [[sftp|SFTP]] and [[ftp|FTP]] protocols.
 +
 +Use the //Automatically reconnect session, if it breaks while idle// checkbox to enable automatic reconnection of sessions, while WinSCP is idle.
 +
 +In //Reconnect after// configure how long will WinSCP wait before reconnection attempt. Note that you can always force earlier attempt manually. The setting applies for foreground sessions only. For [[transfer_queue|background transfers]] the interval is always 2 seconds.
 +
 +Use the //Automatically reconnect session, if it stalls// checkbox to enable automatic reconnection of session, when the server stopped responding. Use //Reconnect after// to set how long should WinSCP keep waiting for response. Note that this value should be higher than //[[ui_login_connection#timeout|Server response timeout]]//. This is supported with [[sftp|SFTP]] and [[scp|SCP]] protocols.
 +
 +In //Keep reconnecting for// configure maximal time WinSCP should attempt to reconnect. Use //Unlimited// to allow WinSCP reconnect indefinitely.
