Delete files after packing

[marcelmuecke]

Hi,
thanks for this very useful tool! I have a feature idea, but don't know, whether this is possible or not.

Sometimes I need to delete huge amounts of files which takes a lot of time via ftp (unfortunately, I don't have shell access). It would be cool to have an option "delete files after packing" so that only the archive remains, which could be deleted quickly.
