I lost pictures when transferring them from a memory card to PC. Now I have a lot of .chk files that I can't open. Is there any software that I don't have to purchase that will open and repair these files and put them back as they should be which is .jpeg files?
The above question is raised in Microsoft Community. In most cases, common Windows users will not see strange files with .chk extension and a folder called Found.000. But sometimes, they find a lot of CHK files appearing in Found.000 folder while files and photos disappear from their hard drive, SD card, USB drive. What are CHK files and can we recover files from Found.000 folder?

Chk files are fragmented files, which are produced when the process of writing files into a volume is stopped in the middle or when files are not saved before the sudden shutdown of your PC. Then the Windows built-in chkdsk (check disk) tool will automatically run and create Found.000 folder and transfer all chk files (fragmented files) into this folder.
To sum up, chk files are just corrupted data produced by check disk tool while Found.000 folder is created by Windows to contain them. And the folder is hidden by default. You need to tick off "hidden folder" in "View" on the top of File Explorer to show this folder.
Usually when you find your files are converted to CHK files, if the files or data are not quite important and there are backups, you don't need to try this CHK file recovery method to recover the data and you can just delete the folder and CHK files contained in it to save the storage space. Of course, you'd better try this method if the files are precious and had no other way to retrieve them.
Before operating, memorize the file path of the Found.000 folder.
Right-click Start Menu and open the Command Prompt (Admin) or you can search in the search bar beside Start Menu.
Input "cd/" into the black window and press [enter]. (cd is short for change directory. "/" is added to change the root directory.)
Input the volume letter (such as d:) the Found.000 folder is in and press [enter]. (Change the working directory to the volume the chk files are in.)
Input "cd Found.000" and hit [enter]. (Change the working directory to the folder chk files are in.)
Input "ren *.chk *.mov" and tap [enter].
After finishing the above procedures, you can go back to the Found.000 folder and see whether the CHK files are restored.
UnCHK is a free and simple tool to recover the CHK files. Running it will help your PC recognize the type of chk files. If successful, it will manage to change the .chk to the right extension names. With the correct extensions, you can easily open the files with default apps. Of course, not all files can be recovered with UnCHK especially when the files are severely damaged.
After trying all the above solutions, if you still cannot recover lost data from CHK files, you can use FonePaw Data Recovery , a professional data recovery tool to recover lost or corrupted photos, videos or files from your memory card or hard drive. Just use the program to scan your memory card, USB flash drive, hard drive with CHK files and see if it can scan out the photos or files you need.

Step 5: After scanning, all deleted files will be presented according to their file types or their paths. You can choose to view the files by "Type List" or "Path List". You can directly go to the Found.000 folder by "Path List".
Step 6: Tick off the files you want to recover. Click the "Recover" button on the right bottom corner to get them back.
If you do not see the files you want, do not feel frustrated immediately and you can, in step 5, try to click "Deep Scan" on the right top corner to scan the files more deeply.
