Hi,
This is a simple guide, but I'm quite happy with this setup so I'm sharing it here 🙂
I was bored to have many QubesIncoming subdirectories in my qubes, after receiving a file I usually move it from there, but I always forget to clean the empty directory.
This command line to add in /rw/config/rc.local will automatically remove all empty sub directories, but not remove /home/user/QubesIncoming itself because it's it's bookmarked in the file browser, it would disappear when deleted.
test ! -d /home/user/QubesIncoming || find '/home/user/QubesIncoming/' -mindepth 1 -type d -exec rmdir '{}' \;
