If I have 10 files I want to transfer and I individually select them and transfer one by one then the option for "Maximal number of transfers at the same time" will transfer that many at once. However, if I select all 10 files and transfer as a group then only one file is transferred at a time. Even if there are no other active transfers.
Is there a way, that I have missed, OR can there be a way to tell WinSCP to use that Maximal setting across and within groups of files to be transferred. In theory, once there is one group left, if there are multiple files in that group then transfer multiple files. If another group is added then as soon as the number drops below maximal then start transferring one per group again.
