Transfer Queue/Background Transfers

To instruct WinSCP to perform the transfer on background, check Transfer on background (add to transfer queue) on transfer options dialog before the transfer. If you do not use the dialog or want to transfer file on background by default, check Transfer on background by default on Background tab of Preferences dialog.

Once you instruct WinSCP to perform the transfer on background, the transfer is added at the end of transfer queue (visualised by background transfers queue list).

WinSCP by default performs at most two background transfers at once. If you schedule more transfers, those will wait in the queue until some previous transfer is finished. For each background transfer WinSCP opens separate connection to the server using the same session option as used for the main session. Once the transfer finishes the connection is kept on background and reused for future transfers.

You can change number of simultaneous transfers on Background tab of Preferences dialog. You can also allow WinSCP to process particular transfer despite the limits.

Alternatively you can instruct WinSCP not to process the queue by default, but wait instead, until you explicitly ask for it.

Once the background transfer finishes, the target directory is reloaded (still on background) and content of the respective file panel is refreshed.

Once you have your transfers scheduled, you can use queue list to manage them.
