Where is Trash?
/home/userName/.local/share/Trash
2.Under Trash
Three files:
info :The deleted files info is here.Include path and date.
files :The files you deleted is here
expunged :It's always empty.
If the file in "files" has no corresponding info in "info",the application don't know how to restore the file.
If you create "haha.txt" in "files",you'll see this file in the file browswer.But you cannot restore "haha.txt" because it has no corresponding info in "info".So you can create "haha.txt.info" in "info" according to certain format.Althought you created this info,you cannot restore "haha.txt" still.Because this is a bug.The trash file browswer only read once "info" when you Log in this computer.When you delete something,the trash file browswer also update its info.If you log out and then login ,you'll find you can restore "haha.txt" now.
If you delete a file "a.txt",you can see "a.txt" in "files" and "a.txt.trashinfo" in "info".If you delete "a.txt.trashinfo",you can still restore a.txt.This seems very strange.This's a bug:The trash browser only update its info when you login and when you delete somefile.
3.Empty the Trash
