I was transferring stuff from a 128GB to a 1000GB card via Card Reader connected to my PC. Not just that, but also transferring screenshots and videos from Switch 1 to Switch 2.
However in doing so, Switch 2 cannot read any of the files and had to delete all data except for the album, which is fine since it was all on cloud. However, Switch 2 still could not read the album from Switch 1.
So, I put the card back into Switch 1, and now somehow Switch 1 can only read screenshots & videos from 2 out of the several games I've played. I checked on my PC and everything in the album folder is still there, uncorrupted, still viewable and watchable from my PC, but neither Switches can see most or all of them. Is there a way I can repair those files by renaming some things?
