Background Tab

The box Maximal number of transfer at the same time defines maximal number of background connections that WinSCP can automatically opened at the same time and thus maximal number of parallel background transfers. If you schedule more transfers the others will wait in queue. You can always instruct WinSCP to process particular transfer despite the limits.

The Transfer on background by default checkbox makes WinSCP to perform all transfers on background. You can always alter this for particular transfer on transfer options dialog (if enabled).

You can check No confirmations for background transfers to avoid overwrite and other confirmations for the background transfer.

The Automatically popup prompts ob background transfers when idle checbox affects how background transfer interacts with user.

Use Remember password of main session for background transfers checkbox to avoid background transfers asking for password. WinSCP will save the main session password and reuse it for background transfer connections. Note that for this WinSCP must keep the password in memory, what may have security implications. If you have the password saved in stored session, what is not recommended at all, the saved password is used automatically for background transfers.

Use Queue List box to control visibility of background transfers queue list. Special view state Hide when Empty (default state) makes the queue list visible, when there is some background transfer in progress or scheduled, only.

Note that visibility of the list can be controlled from main menu too.
