Recover My Files V3.1 (R)
When searching for a "Deleted File", Recover My Files reads the File Allocation Table (FAT) or Master File Table (MFT) to determine if the space used by the deleted file is being occupied by other active files. As only one file can occupy a storage space at any one time, if this happens the deleted file has been overwritten, or partially overwritten, and that part of the deleted file has been destroyed.
The rating system is as follows:
Overwritten: The original file has been completely overwritten and cannot be recovered.
Poor: the search indicates that between 1% and 50% of the file can be recovered.
Medium: the search indicates that between 51% and 90% of the file can be recovered.
Good: the search indicates that between 91% and 99% of the file can be recovered.
Very Good: the complete file can be recovered.
Whilst this rating system is a good indication of the chance of recovery, a preview of your file, if available, is the definitive way to determine if your file can be recovered.
