Un-delete your mistakes

How many times have you deleted a file by complete accident and could not get it back, gone forever is what you think. Well not exactly!

There is a way of getting back your deleted file just as it was before you deleted it. When a file is stored on a windows computer it is giving a place on a table known as the “file allocation table”, then when you delete a file from your computer it is removed from the file allocation table and so you think it is gone, in one way it is however it is not really, for a while after you delete a file it is still on your computer, you cannot see it but it is still there, when you check to see how much free space you have it tells you how much you should have.

After you delete a file or empty the recycle bin the computer just adds some additional characters to where the file was stored, say a file was called 100110 in your memory well when it is deleted the few characters are put in front of it so the file might look something like this: ###100110 when the computer is scanning through the computer and sees this symbol ### before the 100110 it will know to skip the following sequence of 1’s and 0’s. These files will remain on your computer for a while, but if you are putting something large on your computer the space might be required so your old files with the # symbols will be removed.

So if you want to get a file back your best chances of getting the file back would be shortly after you deleted it. You can do this by using a program called UndeletePlus with UndeletePlus you can bring back the files you deleted.

You can retrieve files you deleted off your camera or computer once you connect it to the computer and scan it with the Undelete program.

Try doing this by making a file such as taking a picture on your phone, delete it then connect it to the computer and scan it with the Undelete program you will see loads of files you deleted some of which have been overwritten these are the files that are to late to be retrieved, but then you will see others saying that they can be retrieved so simply select the file you want to get back and click: start undelete, and within a few seconds your file will be back as good as new.

If you want to get your files to go forever after you delete them you have to use a shredder and it will completly wipe out the file when it is deleted.
