It's a sickening feeling, the moment you realise that some important document, or irreplaceable photos have vanished from your computer. But that is no reason to despair. The chances are that the data is still present, even if you know you deleted it. Your computer operating system just does not know how to find it any more.
The four most common reasons for data loss are:
- Deletion. You deleted the file by accident during a disk cleanup, or because you thought it was no longer required. It is not in the Recycle Bin. However, the data will still exist until the space it occupied on the disk is are-used by another file.
