I am transferring a large volume of small files to my server. I have been using the Synchronize feature to mirror the files from my hhd to my server. However unlike when I start a new transfer I cannot find a way to upload the files in the background. This is a problem because I can have up to 9 background transfers at the same time, which vastly improves the speed of the transfers.
How can I use the Synchronize feature to mirror the files, uploading them in the background?
