How to recover chkdsk saved files?

chkdsk ran on a FAT32 SD card. It recovered two directories and several files which it put into files. How can I recover them?

The two directories it saved are in files with the same name as the directories used to be (i.e., "Masterpiece_Mystery_Zen_Ratking_720p_20110731_TTL", "Phantom"). Directory Phantom had several subdirectories.

The files saved are named FILE0000.CHK, FILE0001.CHK, ... FILE0045.CHK. They were all put into a directory called FOUND.000.

Is there any way to recover these files?
Thanks.

I just discovered BOOTEX.LOG on the SD card that was chkdsk'd, if it helps:

One of your disks needs to be checked for consistency. You
may cancel the disk check, but it is strongly recommended
that you continue.

There are two utilities that can rename the .chk files to the correct (almost all) extensions based on the file type.

UnChk

CHK-Mate

The instructions are quite simple. Run the utility, point it to the folder with the .chk files (make a backup of the .chk files first) and wait :)
