Restore/Emptying Trash Through the UI
For a person who does not like to use the command line much, the UI provides the following ways to empty your deleted files from Trash:
Right click and open it.
You can empty Trash direct from down side option
Another way of deleting the Trash is to open the Trash folder from the File Manager and then press the Empty button located at the top-right corner of the window.
This way you Trash will be emptied or restored, restoring/deleting all the files and folders simultaneously.
You can also right-click an individual item and select the Delete from Trash option in order to permanently remove it from your system but deleting items one by one is a time-consuming task.
