Why does deleting things clear storage even though the pc only can’t find it?
In: Technology
Filesystems work like libraries.
When you want to find a book you look up the location in a catalog and then go get it.
Deleting just removes the entry from the catalog so you can’t find it. But the book is still on the shelf somewhere (until it has been replaced by another book).
This is why you can still recover deleted files…you just ignore the catalog and walk through the library and catalog everything yourself.
To truely delete something you must not only delete the catalog entry but you must also replace the book on the shelf by overwriting the old data with garbage.
