MP3 reports cannot open file for writing

[rjsully45]

About two months ago, MP3tag began to refuse the changes I requested for my MP3 files. It instead gave me a message "File D:(whatever)...songtitle...
cannot be opened for writing.

I am using Mp3tag v2.94.

Any ideas on a fix?
Thanks,

What changed 2 months ago?
Who is the owner of the files? (it is not enough to be Administrator)
Are the files OK? See e.g. How to check files for errors?

I don't recall anything unusual. I think I upgraded to a more recent version of MP3tag.
The files seem fine in that they play audio OK.

The Administrator angle is interesting. from time to time I have been getting notices from Windows regarding administrator status.

I see that that the MP3Tag community has recommendations to check for Mp3 file errors. I will try them out and report back.

Thanks for the response, Florian.

Updating MP3tag hardly ever leads to unwritable files.
Files are not necessarily OK if something can be heard.
What happens if you move one of the files ot a completely different folder, e.g. documents? Can you modify the tags there?

I use Mp3Tag to write metadata to the wav files I create from Cubase Pro 12 prior to uploading them to Bandcamp. I also use it to edit the data for work in progress mp3 files that I use to check earlier versions of mix downs.

I have not tried to edit the metadate for a wav file for a while and have updated mp3 tag in the meantime, and have moved from Cubase 9 to 10. I now find I cannot edit wav metadata.

I appreciate the point about checking that Cubase has not somehow created a wav file with the wrong structure, but how can I do this, and if it has, what is the solution. It was the ability to edit metadata for wavs that led me to get mp3Tag (and make a donnation, as it is so useful!).

Thanks

There is a similar report here:

Ver 3.14 bug: file "cannot be opened for writing"

oh, it's a wav file! I opened the file with Nero Wav Editor and saved it again and then had no problem to save a tag. The support for tags of wav fiels in WE is scarce to virutally non-existent. So the windows explorer is yet again no good test environment to check MP3tags tagging capabilities.

Yet, if I save the same wav file again with e.g. Nero WaveEditor then I get a taggable file.
So right now I think that some of the hex editor boffins have to look into it.

I appreciate the point about checking that Cubase has not somehow created a wav file with the wrong structure, but how can I do this, and if it has, what is the solution.

The easiest way is to rewrite the file (lossless) with a tool defined in MP3tag. I had to use it very often because my favorite recording tool used to create wave-files with a wrong header.

User-defined Tools

Example — Re-encode WAV using ffmpeg Some WAV files have an invalid structure or extra junk bytes at some RIFF chunks so re-encoding the file might fix the problems. You can use the excellent ffmpeg command line utility as a user-defined tool from within Mp3tag. [Convert using ffmpeg as a user-defined tool] Name wav2wav Path Please locate the path of your ffmpeg.exe Parameter -i "%_filename_ext%" "%_folderpath%\%_filename%_out.wav"

Can you retry those files with Mp3tag v3.14a?
