chkdisk sometimes converts your folder to file type during the scan. To recover your data, follow the below steps.
- Go to Change folder and search option -> View -> check Show hidden files and uncheck Hide protected operating system files.
- You should see a folder with name "found.***" in your drive. Right-click on that folder and take ownership or grant yourself read/write permission on this folder through the Security tab.
- Now open "found.***" folder. There might be multiple "dir***.chk" folders inside.
- Go through each folder. One of them should have your lost data. You can simply copy/paste from here.
