When you delete a file from your computer using the 'Deleted Rescue' option and even if you emptied the Recycle Bin or deleted by pressing "Shift + Delete" keys. Windows removes the references to the file and file's space is marked as free so the system can re-use it but file's contents, even though you cannot see the file, remains on a drive until this area of the drive is overwritten by another file. So it is possible to recover deleted files until they have been overwritten.
To improve the probability of data rescue, first of all, stop any activity on the drive you are going to recover files from such as writing new data, installing or running programs that could use the drive space.
If data rescue software is installed prior to the file being deleted, your chances of recovery are greatly increased as you can immediately recover files after deletion. If you do not yet have an data rescue tool installed on your computer, avoid installing it to the drive with lost files as it increases the risk of your data being overwritten.
Avoid using your system drive for any tasks that may directly or indirectly write new data on the system drive as it could cause overwriting the lost data and reduce chances of undeleting. The less you use your computer before undeleting, the better your chances of getting your files back.
