I've been using WinSCP for a while now and enjoy it a lot and, have a request/suggestion.
I found when I delete a folder which contains many files and folders and to varying depths, it takes forever to delete that 'folder structure'. In these cases I open a terminal window and voila, I type command line instruction to recursively delete the contained first level folder contents. This option is instantaneous. It deletes the stated folder instantaneously, irrespective of depth.
Here's my thinking; would it be possible for the regular GUI delete from the right-click pop-up menu, to have an option to delete a folder's content using the regular delete command (rm -r folder/) for each folder/file found in the containing folder. Currently it seems it is deleting each folder/file individually, on at a time.
If this was possible the delete in the GUI would be 99% faster.
