Thanks. Yes I've tried to just move the files out and they still open with the older data. When I check there is no different versions of the file old/new.

The reason they had the files in this location before was apparently to make them harder to find lol

It's likely just a case of 'don't put document files in those folders or windows will do funky things to them scenario'.

They're going to use a different folder from now on.
