What is that `Recycle_Bin` directory in my home folder?
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 10 days in that directory. You can suppress the usage of that folder if you place a file called AAA_DONT_SCAVENGE_ME or .aaa_dont_scavenge_me in it.
