When you delete a file, its content physically remains intact on the media, but the occupied space becomes marked as free. Next file saved to the disk may overwrite the contents of the deleted file.
It is very important to make sure that no application writes to the drive or partition where deleted file is located since every new file (even a small one) may overwrite the deleted file.
Tips. What you should do, when you realized that the file you need is deleted:
1. Do not open or close files and applications.
Many applications create temporary files which may overwrite and corrupt your deleted files.
2. Depending on your system configuration, you should perform one of the following action.
3. If deleted files were located on the system disk (usually disk "C:"), or if you have only one logical disk in the system, you should not install any software into the system since it will most likely overwrite your deleted file.
4. We provide an ISO image with NTFS Undelete. You will have to use another computer to burn that image to a CD or DVD. Then just run NTFS Undelete directly from CD.
5. If your deleted files are not located on the system disk, then you can use NTFS Undelete Windows Installer to install the software as usual.
6. Run NTFS Undelete application and locate deleted file you’d like to restore.
7. Always recover files to another disk or partition. Do not recover files to the same partition they were located, otherwise files you are recovering may get corrupted and unrecoverable.
8. That’s it, now you have your files back!
