this might seem a very basic question but i have been thinking about this a lot. The thing i know about deleted files is that it doesn't really disappear from the hard disk. It simply get unlisted from sort of a data structure that contains the files and their info or it get overwritten(not sure). My questions are:
Did i describe it correctly at the beginning? If not please correct me.
Where do deleted files go physically? In what part of the hard disk?
if a storage device has a limited space(it certainly does), How can it contain an endless amount of deleted files along with the actual files in it?
