| - | WinSCP can synchronise content of local directory with remote one or vice versa or even mutually. Find the function in //Commands > Synchronize//. [[ui_synchronize|Synchronize dialog]] will appear, where you can select synchronisation mode and configure options. | + | //This article contains detailed description of synchronizing files. You may want to see [[guide_synchronize|simplified guide]] to the process instead.// |
| - | Once you confirm your options, synchronisation will start. Whenever WinSCP finds some change, it can optionally ask you for confirmation (option //Preview changes//). | + | WinSCP can synchronize content of local directory with remote one or vice versa or even mutually. Find the function in //Commands > Synchronize//. [[ui_synchronize|Synchronize dialog]] will appear, where you can select synchronization mode and configure options. |
| - | Files and directories [[ui_transfer#other_options|excluded from transfer]] are excluded from synchronisation too. | + | Once you confirm your options, WinSCP will collect list of differences in between the directories. If option //Preview changes// is enabled, you will be presented with the [[ui_synchronize_checklist|synchronization checklist]], where you can select those synchronization actions you want to actually apply. |
| - | Before using the function make sure that WinSCP knows correct timestamps of remote files, to avoid losing data. | + | You can select files and directories for synchronization the same way you [[ui_transfer_custom#other|select them for file transfer]]. |
| - | ===== Synchronisation Modes ===== | + | Before using the function make sure that WinSCP knows correct [[timestamps]] of remote files, to avoid losing data. |
| - | There are three direction modes for synchronisation. | + | |
| - | In //Local// mode, changes from remote directory are applied to local directory. Only local directory is modified. If file in remote directory is newer than the same file in local directory, the local file is updated. The remote files not existing in local directory are optionally downloaded too (disable option //Existing files only//). The local files not existing in remote directory are optionally deleted (enable option //Delete files//). | + | If you use WinSCP to synchronize your files only, you can use ''[[commandline#operations|/synchronize]]'' to quickly open [[ui_synchronize|Synchronize dialog]]. |
| - | //Remote// mode is the same as //Local//, just in an opposite direction. | + | ===== [[direction]] Synchronization Direction ===== |
| + | There are three possible directions (targets) of synchronization. | ||
| - | In //Both// mode, both local and remote directories can be modified. The newer files are transfered to the opposite directory. The files not existing in an opposite directory are optionally transfered too (enable option //Existing files only//). In other words, no files are deleted. | + | With //Local// direction, changes from remote directory (source) are applied to local directory (target). Only the local directory is modified. |
| + | //Remote// mode is the same as //Local//, just in an opposite direction: changes from the local directory (source) are applied to the remote directory (target). Only the remote directory is modified. | ||
| + | |||
| + | In //Both// mode, both local and remote directories can be modified (both can act as both source and target). | ||
| + | |||
| + | ===== [[mode]] Synchronization Mode ===== | ||
| + | There are three modes of synchronization. | ||
| + | |||
| + | With //Synchronize files// mode, files that are newer in a source directory than in a target directory are transferred to the target directory. Files in the source directory not present in the target directory are by default transferred as well (disable this using the option //Existing files only//). Files in the target directory not present in the source directory can optionally be deleted (enable option //Delete files//). In //Both// mode (see above), files not present in an opposite directory are considered new, hence they are transferred (unless //Existing files only// is enabled), but never deleted. In other words, in //Both// mode, no file is ever deleted. | ||
| + | |||
| + | With //Mirror files// mode, different (both newer and older) files in the source directory are transferred to the target directory. Otherwise the mode is the same as //Synchronize files//. | ||
| + | |||
| + | With //Synchronize timestamps// mode, timestamps of target files are updated to match timestamps of source files. It will not do any transfers, nor delete anything. Simply, whenever it finds the same file in both directories, it updates a timestamp of a target file to match the one of a source file. In //Both// mode, it always updates the older timestamp. The mode is available with [[sftp|SFTP protocol]] only. | ||
| + | |||
| + | ===== Automating Synchronization ===== | ||
| + | To automate synchronization use scripting command ''[[scriptcommand_synchronize|synchronize]]'' or .NET assembly method ''[[library_session_synchronizedirectories|Session.SynchronizeDirectories]]''. | ||
