as this function has a preview you should see how and where the patterns match. If you are not sure, then please provide a screenshot of a real filename as every space character and other characters counts. ![grafik](https://community.mp3tag.de/uploads/default/original/2X/8/82016e36921752322b0b6c81e065b1543e98e43f.png) ---

> [@djfrankjoy](#): > > can this be made as a action comand ? How often will this happen in the life of a file? And with a look at the problems that arose initially, wouldn't it be better to control the treated files with a filter? e.g. `%_filename% MATCHES ".*_\d+_\d+$"` Then you could create an action of the type "Replace with regular expression" for \_FILENAME Search string: `(.*_\d+)_\d+$` Replace with: $1 This expression only looks if there are 2 elements consisting of numbers at the end - it does not look whether they are the same. ---

i dont know how often the bug will hold on. momentary have 160 tunes with that bug and next time more. i will test it the next days and thank you really very very much for your help and i think if its replace the last number it will make my solution. i hope i will understand the commands 🙂 ---

> [@djfrankjoy](#): > > i dont know how often the bug will hold on. I would still use the converter as you can control better what happens to the data - an action is executed more or less in the background. But you will find the best way for you. ---

the tag tag is not good because i dont want to change the tag, even the tag is okay, just the filename is wrong. if you have an idea how to change it all with an action command to delete the last number in the filename it would be awesome. ---

I still see the `$` at the end of the regular expression - what happens if you delete that? ---

Are you sure that you try it on the track with the filename `artist_545155_545155.mp3` @ohrenkino's regular expression `(.*_\d+)_\d+` works fine here: ![RemoveNumbersAfterLastUnderscore](https://community.mp3tag.de/uploads/default/original/2X/c/c1c9b8565d632b67fa39840286fbf34bbb692cb5.gif) Could it be that your underscore is not a real underscore, just a character that looks like this? Please copy your filename from Windows File Explorer in this webpage: [https://www.babelstone.co.uk/Unicode/whatisit.html](https://www.babelstone.co.uk/Unicode/whatisit.html) There you can see every single character and also if your underscore is a "real" underscore. A real underscore would appear as "LOW LINE" on the linked analyzing webpage: ![image](https://community.mp3tag.de/uploads/default/original/2X/4/4e7dc4a8420b234162b6a38f0e7b33214afbd4d6.png) ---

> [@djfrankjoy](#): > > i replied that i tryed both variants > but nothing happens With the data that you have supplied that result is not plausible. And as it seems to be rather tricky to maintain an action that works so clandestine, I would prefer the Converter\>Filename-Filename as that shows immedidately if the expression leads to success or not. Or an alternative: rewrite the whole filename with Converter\>Tag-Filename and Format string: %artist%\_%numberfield% (where you have to replace %numberfield% with the real fieldname) ---
