First congrats on the first Win10 Store version, just saw a post on mspoweruser.com.
Long time user and donator I immediately downloaded it and installed.
However I am unable to use my old standalone configuration.zip file with the new app because I can't see the MP3Tag directory in the \apps\roaming\mp3tag directory to put it in. It appears to be invisible (?).
When I save a blank config out of the new store app it thinks it's creating it and prompts to overwrite it, but I still can't see the MP3Tag directory. Any hints? Thanks.
Thanks Florian, I was able to locate the directory and dropped my standalone version's data/config info into it and now it's the same on the Windows 10 app. It even maintained the albumartdownloader helper external tool link.
