Hi,

Hoping someone can help me, been going round in circles trying to figure out.

I have a bunch of files with the name format :  
Holiday [LNTG Muscle Mix] [45263224]

I am trying to use the Filename - Tag function to add a title for each file, ideally in the format :  
Holiday [LNTG Muscle Mix]

The closest I have got is by using the following :  
%title% [%title%] [%dummy%]  
which gives me the Title :  
Holiday LNTG Muscle Mix

Ideally, I would like to keep the square brackets around 'LNTG Muscle Mix'  
Anyone know if this is possible?

Many thanks for any help

You could try  
`%title%] [%dummy%`  
to get at least the opening bracket.  
You could then add the closing bracket with  
Convert\>Tag-Tag for TITLE  
Format string: `%title%]`

If this is something that may happen to only some files, then you could filter for TITLEs with an opening but not closing bracket with:  
`%title% HAS [AND NOT %title% HAS]`

Thanks, this almost worked for me, but when adding the Format string : %title%], I get Invalid syntax response. Are square brackets not allowed here?

You can try to escape the special char `]` with  
`%TITLE%']'`

From the [documentation](https://docs.mp3tag.de/format/#characters-with-special-functionality):

If you do not have to use the converter, you could also use an action of the type "Guess value"  
Source: `$regexp(%_filename%,'(.*) \[\d+\]',$1)`  
Target fields: `%title%`
