PhotoRec Tutorial: How to Use PhotoRec

PhotoRec is an effective file recovery program, which enables you to recover various file types, including multimedia, documents, archives and much more from a range of hard storages (hard disks, CD-ROMs, usbs, memory cards etc.). Obviously, it can also recover photos from your digital camera (supports all the main camera brands: Canon, Nikon, Olympus, Pentax etc.). Works with all the main file systems: FAT, NTFS, HFS+, exFAT, ext2/ext3/ext4. Even if your file system was severely damaged or formatted, PhotoRec will still help. The program is free and supports more than 440 different file types (around 270 file type families). PhotoRec uses read-only access, ensuring the safety of every recovery process.

How to use PhotoRec?

Step 1. When you start working with PhotoRec, first of all you need to choose the disk you wish to work with. Though, to do this, you need to make sure that you’re using the administrator account.

  • Click Search to start the recovery process;
  • Click Options to change the settings;

Step 3. Options Menu.

  • Paranoid – recoverable files are verified, invalid ones – rejected;
  • Allow Partial Last Cylinder – determines how the disk geometry is defined;
  • Keep Corrupted Files – to keep all the files, even the damaged ones;
  • Expert Mode – allows you to force the file system block size;
  • Low Memory – enable/disable your system’s low memory usage if it crashes during the recovery process;

P.S. change these settings only if you are 100% sure what you are doing;

Step 9. See the outcome, when the recovery process finishes. It is also advised to scan the recovered files with your antivirus software, as PhotoRec might have undeleted some Trojans or other harmful files.

The relationship and differences between PhotoRec and Testdisk

Essentially, PhotoRec is just a companion utility to TestDisk (PhotoRec is included in the original TestDisk download folder). Both PhotoRec and TestDisk are free software used for recovery/test/fixing operations. They work with the low level data, below the OS. In both programs there is no mouse, instead, Up/Down/Enter buttons are used. None of them needs to be installed on a computer for user to operate them, making them very portable and suitable for inclusion on boot disks. Interface isn’t that user-friendly, but, indeed, quite straightforward and not too complicated. In addition, there are plenty of online guides, explaining how to use PhotoRec and TestDisk. While TestDisk is mostly designed to recover corrupted partitions, PhotoRec specializes in restoring numerous file types, not just image files, as some might think. Both tools run on the most OS, including Windows, Linux, Mac OS X, DOS, Solaris etc.
