Hello, I hope you are well 🙂 I have a question for you, I hope you can help me. How can I add a character in the filename field to a long list of files whose ID always varies? For example, I have something like: 2019-01-01 [v=aaabbbcccmmm] name of a file.mp4 2019-02-05 [v=222bbbcccmmm] another name of a file.mp4 2020-04-11 [v=777bdbcccmmm] yes another name.mp4 2020-04-20 [v=a5abbbccc3mm] the name you want.mp4 2020-04-21 [v=aarbbbcrcmmm] Mary had a little lambm.mp4 And I just want to add a long dash (—) to it right after that code. So the above should look like this: 2019-01-01 [v=aaabbbcccmmm] — name of a file.mp4 2019-02-05 [v=222bbbcccmmm] — another name of a file.mp4 2020-04-11 [v=777bdbcccmmm] — yes another name.mp4 2020-04-20 [v=a5abbbccc3mm] — the name you want.mp4 2020-04-21 [v=aarbbbcrcmmm] — Mary had a little lamb.mp4 after ] then a space then — then space and finally the name of the video Maybe there is some function in mp3 like: REPLACE [v=\*] \* .mp4 BY [v = \*] — \* .mp4 ? There are a lot of files so I need a way to do it in bulk, instead of adding that script file by file. Any help is appreciated ---

Thank you, ohrenkino, but I don't understand what you meant by this: > [@ohrenkino](#): > > Or use Convert\>Filename-Filename > Source mask: `%1] %2` > Target mask: `%1] — %2` ---

Are you even using Mp3tag, i.e. the piece of software this forum is all about? ---

> [@ohrenkino](#): > > **Source mask: `%1] %2`** > **Target mask: `%1] — %2`** Sorry, the further parameters. What I don't understand is that about "Source mask" and "Target mask" and the% percentages. Where do I find that option within mp3tag? and what do I do with that. I don't know how to apply this that you wrote to me. ---

Press Alt+0151 to get the em dash. ---
