"""File Manager Utilities
Trash according to Freedesktop.org:
For every user2 a “home trash” directory MUST be available.
Its name and location are $XDG_DATA_HOME/Trash
The implementation also MUST check that this directory is not a symbolic link.
If these checks fail, the implementation MUST NOT use this directory.
See videothumb lines 226,227.
A trash directory contains two subdirectories, named info and files.
$trash/files directory contains the files that were trashed.
$trash/info directory contains an “information file” for every file
This file MUST have the same name as the deleted file with extension “.trashinfo”.
“Path” contains the original location of the file/directory.
“DeletionDate” contains the date and time when the file/directory was trashed.
When trashing a file the program MUST create the $trash/info first.
