Hmm. I downloaded your file - it is a 7D raw file that is only 5.5MB. Something is amiss. The EXIF is intact. Here is a screenshot of the file viewed in DPP. After trying to solve a similar issue in this thread:
https://photography-on-the.net …/showthread.php?t=1399261
it appears that CR2 files have a small JPEG and a full-sized JPEG embedded in them. in the other thread, the small JPEG was intact, but everything else was toast.
In your case, the FUL SIZE JPEG is intact - 5,184 x 3,456 pixels / 3.6 MB - I extracted it using dcraw:
Here is a Dropbox link to download it:

It is almost as if the raw file ... is not a raw file. Did you accidentally rename your jpegs with a .cr2 file extension? I think that may be what happened, as raw files from the camera have a ".CR2" extension (capital letters) not ".cr2" (lower case letters, like you file). Maybe? Either that or the file recovery program was able to recover the EXIF header and JPEG data, but ignored or was not able to recover the raw data in the file.
What solved the other poster's problem was connecting the camera to the computer with the card in the camera, and copying the files to the computer that way (versus taking the card out of the computer and using a card reader).
