Keep Remote Directory up to Date

Keep remote directory up to date is a unique feature of WinSCP. With it you may let WinSCP watch for changes in a local directory and have it automatically reflect the changes on the selected remote directory.

Using it, you can, with some limitations, work with local files using your favorite tools and the effect would be as if you were working with remote files directly. In other words, the feature partially replaces commercial remote directory drive mapping tools.

Find the function in Commands > Keep Remote Directory up to Date. The Options dialog will appear.

If you use WinSCP to synchronize your files only, you can use command-line parameter /keepuptodate to quickly open options dialog.

Note that you will be warned if number of subdirectories to be watched exceeds 500. Watching for changes in large number of directories can significantly degrade the performance of your computer.

How It Works

Once you start the function, WinSCP will register to receive notification whenever something changes in the selected local directory (and optionally in all its subdirectories). Once you make a change, for example when you save file in your favorite editor, WinSCP will receive notification about the change in the respective directory. Then it will perform synchronization of the local directory with the corresponding remote directory. Thus your change will be automatically reflected on the remote side.

WinSCP can even (optionally) delete remote files when you delete local files.

You can select files and directories for to be kept up to date the same way you select them for file transfer.

Before using the function you should know that:

  • WinSCP must know the correct timestamps of remote files, to avoid losing data.
  • WinSCP will only detect that something has changed in the directory; it won’t know what the specific change was. So it must perform a full synchronization of that directory. As a result it may upload not only the file changed just at the moment but any file that is out of sync. In other words, you should start the Keep remote directory up to date function only when the selected local and remote directories are already completely (or almost completely) synchronized. You can make WinSCP do this automatically for you, by checking option Synchronize on start.
  • When you rename a file or directory, WinSCP will see it as removal of one file and addition of another and it will reflect the change on remote directory as such. So it is not recommended to use the function to “rename” large files and directories. You should do this manually.

Automation

For automation, use scripting command keepuptodate.
