Have you ever deleted a data/file either by mistake or on purpose, and wished you could reverse it but it appears it is already too late? That could also occur when the system crashes or you encountered a malware attack.
Deleting is simply the process of removing the "path" or reference to access a particular file or data, leaving the space free for other data to be copied in the place. Therefore the computer or device could no longer read the deleted file.

When you delete in some device, it simply enters the recycle bin where you can simply go to either restore/retrieve it or erase it from the system. But what if you had deleted in both the device and the recycle bin?
Deleting is analogous to a library index card. This card simply shows us where the books are located. You have the science section, the public records, the art section, etc. You can locate any of books in this library using this index card. Deleting is throwing away this index card. The books (files) are still there but you can no longer access it ( the device cannot read it) since the card index system (directory or path) is missing.
Since the files are still there you could retrieve or undelete the deleted files by going to the directory and retrieving it.
It is simple, a computer finds it easier to remove reference to files instead of to overwrite it with other data to avoid recovery.
It is a good thing that you can recover mistakenly deleted important deleted file or folders. The bad is that sensitive data/ financial records on your hard drive/memory that you deleted can be recovered by data retrieval method! I know a paranoid man that never resells his phone or PC for fear someone may retrieve some deleted data on it. One of such deleted file recovering software is called recuva,etc.
