I am fairly new to Linux, Ubuntu, etc,
I am running lUbuntu 18.04.5.
Please note that I need to be given explicit instructions whenever I have to use Terminal (command line).
With my being so inexperienced and unfamiliar, I do not know how to empty the Trash folder on an external USB HDD (which I have been using for backing up my home folder).
I can see the Trash folder (which is called .Trash-1000) in the external USB HDD, using the GUI of the file manager for lUbuntu (which is called PCManFM). However, I do not see any way to empty the trash folder using PCManFM.
I am willing to use Terminal to empty the Trash folder, but I would need explicit instructions.

This is just a copy/paste from https://lubuntu.me/pcmanfm-empty-trash-menu/, so all thanks should go to RedWolf
Note: A user at the Lubuntu site also mentions in comments (which I can't test as I already have
zenity
installed)
