Hi how can i remove numbers

Hi how can i remove numbers for this mp3 files

It would easiest to rename the files with Convert>Tag-Filename
Format string: %artist% - %title%
as I assume that the field TITLE does not have the number.

Doesn t works must be some code to remove the numbers

Import the data from the filename to the tags:
Convert>Filename-Tag
Format string: %artist% - %title%

Then use Convert>Tag-Tag for TITLE with
Format string: $regexp(%title%,(.*)\d+,$1)

Then use Convert>Tag-Filename
Format string: %artist% - %title%

It is my opinion that if you really insist on tweaking only the filename without tagging the files, look out for a good file renaming utility as MP3tag is way over the top for that task.
