Most people, especially individuals who are not technically minded, look at a data file to be deleted when the Delete button is pressed for a computer system.
In most cases, data deleted by normal methods may be easily recovered, depending on how exactly the data in question has been erased.
There are typically three ways that data may be deleted from a pc system, these are as follows:
- Delete to Recycle Bin (Windows os's only)
- 'Permanent deletion'
- Secure erasure by overwriting data
Deleting data when using the first method does not necessarily actually delete files whatsoever, it just moves them to a different part of a hard disk, in a folder termed the Recycle Bin. These files may be restored by going in the Recycle Bin, right-clicking on the relevant file, and deciding on the Restore File option.
Files which were 'permanently deleted' are actually just marked as deleted by way of the operating system, with the place that the file takes up being marked as readily available use by other file types.
This means that files deleted in this fashion are actually still there until overwritten by the operating system.
