I have several context menu commands to rename music files from mp3 tags.

I've been using them for years, but since the latest update (13.25) they don't work at all. Is this a known problem?

Thanks.

No it's not. I think if Rename had stopped working we'd have more reports by now.

What commands do they run?

Here's one:

```auto
Select *.mp3
Rename REGEXP TO="{mp3track|#2} - {mp3title}.mp3" TYPE=files FILEINFO CASE=allwords

```

Opus seems to dislike `FILEINFO` now (it's been retired long time ago). `REGEXP` is not needed here but causes no harm.

The issue is using `REGEXP` mode with an empty "from" pattern. A change in the previous version meant this stopped working - although I think it's strictly incorrect and wasn't ever explicitly supported, it did use to work. We'll make it work again in the next update.

In the meantime adding `PATTERN=".*"` should make it work again.

Where do I add that?

Any chance you can show me the complete code that I should replace the above with..."

Thanks for your help. I REALLY appreciate it.

Probably something like:

```auto
Select *.mp3
Rename REGEXP PATTERN=".*" TO="{mp3track|#2} - {mp3title}.mp3" TYPE=files FILEINFO CASE=allwords

```

Seems to work.

Many thanks!

Could be simplified slightly, removing the need for the select command and a few arguments:

```plaintext
Rename FROM="*.mp3" PATTERN="*" TO="{mp3track|#2} - {mp3title}" IGNOREEXT TYPE=files CASE=allwords

```

That will rename all \*.mp3 files in the current folder without having to select them.
