What happens when deleting a file

by - March 16, 2020


Ooops... I deleted my pics, videos, files, etc....

Let's try to see what happens when items are deleted from our devices

PC: Basically in a PC deleted files go to the Recycle bin, trash or any name the PC gives it according to the operating system.

Once here the files will no longer appear in there normal places but in the Recycle bin.

A file goes here because when you delete it, the pointer is changed or deleted.

The space the file occupied remains the same since it's still in the computer.

If you want to permanently get rid of a file you go to the bin and delete it again or press shift+ delete while deleting it.

A permanently deleted file is basically a file whose reference to the hard drive is deleted and in this case, the computer cannot "see" the file. The computer forgets where the file was or whether it even existed. The reason why it's not deleted completely is that the device is trying to save on computing power.

Imagine arranging the keys of a keyboard to QWERTZ, then the user is done and instead of rearranging the keys in a-z fashion the computer just forgets how that arrangement was QWERTZ and then next time the user needs the keys the computer just arranges the keys from QWERTZ (unknown) to let's say Dvorak thus skipping the a-z all together instead of doing 3 steps the computer does 2.

This space is left free for another file to occupy. However, the file remains on the hard drive until another file or part of another file is saved to the same location.

Therefore when deleting a file the computer just removes the reference of the file which causes it to shift to the recycle bin hence explaining why permanently deleting a file is harder since it involves rewriting the disk space.

Can a permanently deleted file in a PC be recovered?

The answer is Yes... It can be recovered by software designed to rebuild the header of the deleted file.

This software is sold and is available locally.

One can also seek the assistance of East Africa Data handlers who are experts in this.


The deleted files can also be made not to be recovered again by doing the so-called Low-level formatting also known as Zero fillings.

This basically involves rewriting the space occupied in the hard drive by zeros to make it invisible.

This is so technical and near impossible so giving us a conclusion that once a file gets to the hard drive it's never completely lost.


Thanks for reading,
