What Happens To Deleted Computer Files and Data?

In most cases, delete files, folders and other forms of computer data are forwarded to the Recycle Bin, in case accidental deletion took place and the information needs to be recovered. There are some instances when deleted information is diverted and never reaches the bin. What most people do not realize is that, when the information is emptied from the Recycle Bin, it has not been deleted at all. The successful recovery of these files and other electronic tidbits can be accomplished, since they still reside within the system.

So, what happens to the data after the Recycle Bin has been emptied? In reality, the items that are contained within the bin have not been deleted – only the signs that show the electronic path to them have been eradicated. In other words, the information is still contained within the hard drive, but the signs which tell the system where they are located are destroyed, so that the computer does not recognize the fact that they are still residing within its memory. This is the reason that the recovery of deleted data can be accomplished. It was never actually gone, to begin with.

These signs, called "pointers", are the indicators that data is present within the structure of the computer. Without them, the common user believes that the information has been removed. I.T. professionals, on the other hand, possess the knowledge and necessary tools for the recovery of this data.

Though recovery of deleted data can be performed when these pointers have been erased, the chances of complete recovery diminish as times passes. This is due to the fact that the hard drive will eventually rewrite newly stored information over top of the previously stored data that was targeted for deletion. It typically takes quite awhile for this to take place, but will - inevitably - happen at some point in the future.
