I guess You must have wondered if deleted files were truly erased from your device.Continue reading to get the answer to this question.When files are deleted, they are never truly erazed from
memory, every device OS works with the same storage option locally.

A deleted file simply means the file location is no longer accessible by the device therefore won’t be visible for you to use anymore. But this doesn’t mean the file isn’t present in your device.With a proper magnetizing device, you can always retrieve deleted files. The binary codes are only hashed in memory and the pointer to them is no longer
known.A proper example to this can be a music file on your device.

When you download a music to your phone and then someone else takes the phone to rename and change the folder which that music is been saved without telling u.

You will not know where the music is because you no longer know the new location and name used in saving it.This is quite similar to how deleted files are in the device. They were never deleted.
Your device just couldn’t remember the directory to the file.
