When choosing a digital media recovery tool for memory card recovery there is only one criteria of substance. That is the ability of your digital photo recovery program to scan for and reconstruct camera RAW files. These RAW files are the original file format as established by your camera manufacturer and used to store your picture onto the camera memory card at the time that picture is taken. Programs available to recover memory card files must be able to recognize these special file types along with all of the conventional file types the RAW file is eventually converted to.
After transfer and conversion onto your computer’s hard drive that same Canon, Nikon, Olympus or Minolta file may now be a simple JPEG. Should you accidentally delete a file in that format you want to be able to search for it as well. The key to choosing the best memory card recovery program is to find one that will recognize all of the needed file types on both camera memory cards and your computer’s hard drive.
