What is that `Recycle_Bin` directory in my home folder?
This folder only appears if you work with Windows as well. Our Samba servers are configured, that they move deleted files into this directory. Every night a script on our servers deletes then the files which were longer than 24 hours in that directory. You can suppress the usage of that folder if you place a file called AAA_DONT_SCAVENGE_ME in it.
