This just cropped up today 20260114. With MP3’s only from Ligonier Ministries, I can remove a tag, but when MP3 Tag adds a tag, it is unable to save the file. I get the message, ‘“Cannot write file “[file path]” Do you want to retry?”’ Worked fine until today. Other MP3’s from other sources have no …

CHANGELOG: Mp3tag v3.33 [excerpt] [2026-01-18] FIX: added workaround for issue introduced by Windows Update where increasing the file size (e.g., when adding cover art) gave an error 380 for files on file systems backed by cloud storage (e.g., OneDrive or Dropbox). (#70522, #70497, #70490, #70…

I had a look at the example file you sent via email, and couldn't spot any issues with the file itself. Is the file locked by a different tool, for example an audio player?

UPDATE: I learned what the culprit was, but I don't know the fix. It was Windows Update. I also don't know why it would only effect MP3's from one source as I described in the earlier version of this post, (that I know about so far). I went to my laptop which had not yet installed the latest Windows…

I’m on the latest version of MP3 Tag. please see my own Reply about Windows Update. Thanks.

I tried the above suggestion about renaming to MP4. Didn’t work. I also tried Saving As with the audio editor, as well as re-encoding with Replay Converter with Copy Metadata turned off. Still didn’t work.

[image] pgchase: I also don't know why it would only effect MP3's from one source Can you confirm that only MP3s from Ligonier are affected? (This sounds very strange, and I can't see how it could be possible.) Could you please try to edit new MP3s from other sources in Mp3tag on devices wi…

With KB5073724 applied, I can confirm that only files from Ligonier are exhibiting this problem. I can open the file with MP3 Tag, remove the cover art and successfully save the file. It’s when I try to replace the cover art, that MP3 Tag says it cannot write to the file. I get podcasts from multip…

I found Puddletag on Linux, and it worked. I gave it a Ligonier file with no cover art, and added an image from my cover art folder, pressed OK, and that was it. So it can be done, away from this latest Windows update and whatever they broke.

You have yet to answer an important question. [image] Florian: Is the file locked by a different tool, for example an audio player? Is there a player or library manager open and active while you are trying to edit these music files with mp3tag? Windows Media Player or whatever iteration the…
