What is the ".Trash-1000" folder and how to delete it?

Solution 1:

This is the folder of you paperbin.
If you delete something it will not be deleted from disk. It will be moved to this folder instead.

Try to empty the paperbin or delete the folder with the terminal-command as root:

sudo rm -rf /path/to/folder/.Trash-1000

Solution 2:

GNOMEish file managers need a place to put the trashed files.

• Deleted files on your "home" partition go to: /home/username/.local/share/Trash
• Deleted files on other partitions can't be copied there for performance and space reasons.

So it tries to put them in the /.Trash-$UID folder. Without rw access to that folder, no trash.

Run this bash in the partition root as the user who needs a trash.

sudo mkdir .Trash-$UID && sudo chown $USER:$USER .Trash-$UID

You can delete this folder and secure the partition / to disable that feature.

sudo rm -rf .Trash-xxxx
sodo chown root:root /thepartition
