/*
Hi Koldo,

I checked the functions in Functions4U. Here are some notes about trashing:

    * On older systems, the trash folder was $HOME/.Trash
    * Your implementation of disregards the folder $HOME/.local/share/trash/info. You should create
    there a .trashinfo file when moving something in trash and delete it when deleting corresponding file permanently.
    * If you delete something on different partition than $HOME, you should also check if .Trash-XXXX
    exists in root of that partition (XXXX is id of user who deleted the files in it).

.local/share/Trash/files
.local/share/Trash/info

A file every time a file is removed with

KK.trashinfo
[Trash Info]
Path=/home/pubuntu/KK
DeletionDate=2010-05-19T18:00:52


You might also be interested in following:

    * Official trash specification from freedesktop.org
    * Project implementing command line access to trash (unfortunately in python) according to the specification mentioned above


Hope this might help Smile It definitely learned me a lot of new things Very Happy

Best regards,
Honza
