I recently uploaded a large directory tree from my laptop to a cloud instance. Upon completing the upload Filezilla reported 3 files could not be transferred.
Is there some way I can find out which files were not transferred?
There should be a tab at the bottom called "Failed Transfers". If you click on it, it'll show what files failed to transfer. I can't get my own screenshot of the tab at this time, but below is a screenshot from the official website, which shows the failed transfers tab at the bottom of the screen.
