See the optons Ctrl-O
Preserve modification time...

Ok, thanks, good to know. But why does the script update the modification time of the files that are not even being renamed? Where can I log a bug?

This is still not a bug:

> Just for clarification: Mp3tag always writes metadata to the files when told so without examining first, whether saving it would result in any actual change to the file. This is by design and not considered a bug.

A filter would reduce the number of treated files.

Ok, a filter was mentioned before. Can we apply the if check as a filter so that's done to remove files before the metadata is added?

Wouldn't it be time to dig into the documentation

or search the forum for questions like

> Hello there, I am fairly new to using this software but can already see it's power. One thing I have noticed though is that it would be extremely useful if a filter could be added to an action, rather than having to remember or select a filter used previously in a specific scenario. Have you previously considered it and is it likely to be implemented?

That's a fair call out, thanks hopefully can get back to this next month.
