I believe this problem started with v2.23o. I keep losing the filename and path as soon as I click on a file and get a save error because I am saving to a filename with a null string. I uninstalled/reinstalled v2.23q and the problem went away, but so did a lot of my settings, so I resurrected a copy of Mp3tag.reg I saved just before I uninstalled and restored it. The problem is back and Mp3tag is not useable. I'll try to send you the REG file.
P.S. I repeated the uninstall/reinstall of v2.23q and this time edited the registry file I sent to Florian via email to restore only those things that I really needed, mostly lists and the sequence of my actions. The program does not lose the filename or path of selected files and is back to normal.

Sorry, I can't reproduce the problem here.
It would be great, if you can find a way to reproduce the problem with the latest Development Build. Maybe it's caused by a special sequence of functions executed!?
Best regards,

I don't think so, because when the problem was there, the first thing I did going in was to click on a file. Immediately the filename and path fields went blank. Trying to save the tag showed that those fields were blank in every way. I suspect this entry in the registry:
[HKEY\_CURRENT\_USER\Software\Moebius\Mp3tag\Settings]
"TagFields"="ALBUMBPMCOMPOSERGENRECOPYRIGHTDATE
PLAYLISTDELAYENCODEDBYLYRICISTFILETYPETIMECONTENTGROUP

Which had different delimiters before:
[HKEY\_CURRENT\_USER\Software\Moebius\Mp3tag\Settings]
"TagFields"="ALBUM\ARTIST\BAND\BPM\COMMENT\COMPOSER\CONDUCTOR
\CONTENTGROUP\COPYRIGHT\DATE\ENCODEDBY\ENCODERSETTINGS

\WWWAUDIOSOURCE\WWWCOMMERCIALINFO\WWWCOPYRIGHT\WWWPAYMENT
\WWWPUBLISHER\WWWRADIOPAGE\WWWUSER\YEAR"
Could I have gotten messed up by restoring the latter into a version that expects the first entry? The problem however, started before I ever tried to restore the registry. Could it possibly be a problem related to skipping a release that handled the delimiter change?

I've never changed anything regarding the delimiter handling of this TagField registry key - it's \v since the beginning.
But I've changed the whole filepath and folderpath handling to version 2.23i, so I guess that it has nothing to do with the registry settings.
Can you reproduce it with 2.23q?
Best regards,

Yes, I can reproduce it by executing the Mp3tag.reg file I sent you. I have known some versions of REGEDIT to improperly write REG files. Is the file written to the registry or extracted from it?

Thanks for pointing me to this problem. I did a code review for all parts in Mp3tag which are handling with filenames and found the bug which occured at least 7 times in the whole program and was caused by the change to the file view's column handling.
It had nothing to do with registry handling but with asking the GUI for filenames/foldernames (the file view) instead of querying them through the backend - duh, this code was from my early programming days 
Thanks!

BTW: The bug should be fixed with the current Development Build and was a "Big Bug" this time 😉
