I have a file (m4b audiobook) that I can't tag. I just get the message 'can't open file for writing' yet I can rename the file in Windows Explorer. After checking the file (it was read only) I corrected read and permissions, restarted Win 10, installed the latest MP3Tag, scanned the drive, installed and used an unlock program on it and still can't tag it. I have had issues recently where randomly tagging an album, I would have a similar issue with one file not writing then would write when I ran the action a second time. Any suggestions on what else I could look at?
There are other files in the same drive and folder with the same issue and some with no issues.
I have previously tagged these files and moved them several times around my home network and am trying to retag differently to match a new scheme.
I was able to edit tags in AIMP (Portable Version) but not VLC. Once I change a tag in AIMP I can then write tags to that file in MP3TAG
