What Happens When You Press The Delete Key

By Brian Shaw


Most of us think the moment we hit that 'delete ' button, the data is gone and lost to oblivion. Not so; Even if the file can't be seen in the catalog structure, it really exists in a safe memory area. If you change your decision and need it back, it can be pulled out from storage.

Next time you hit the remove key (granted that you're not modifying with your Windows operating software) you can be sure the file at once goes to the Recycle Bin. This is a room Microsoft gives us in case we are fickle-minded and want the deleted files again. Then we just have to rummage through this digital rubbish and easily recover our deleted files.

But when you disable the recycle bin, things go differently. It gets removed as such, but in reality what's actually removed is simply the link making reference to the file. It is like removing the index of a page in a book and not tearing out the particular page from the book.

Your hard disk is of course not infinite and eventually, it will run right out of space to contain the files you deleted. In a case of that type, the operating system will overwrite (or write over) the old deleted files with the more recent ones. This suggests that those files you removed last year have greater chances of having been overwritten while the ones you deleted an hour gone aren't. This also suggests the files removed lately can be easier recovered than the ones which have been removed a while back.

Removed files, even those which have been emptied from the recycle bin, can be recovered by data recovery methodologies. Actually because of the advances in info recovery technology, even those which have been overwritten for numerous times can still be retrieved, albeit not completely untouched in some cases.
