Hello!
What I want to do with Convert -> Actions is:
Original file: Name of the song - 1 Title title title
Modified file: Name of the song - Title title title
Remove the number 1 and the white space before the title.
I have tried several ways, but it eliminates all the whiet spaces in the title and I only want the ones before the title.
Thanks for the help!
What do you want to change:
Please give a concrete example for a file.
It is not at all clear to me where the difference is between the name of a song and its title.
If you have filled the tag fields, I would suggest that you create a new filename with the function "Convert>Tag-Filename".
It would have been nice to see the "several ways" you tried because perhaps just a little correction would have done it.
If you insist to fiddle about with the filename only, try
Convert>Tag-Tag for _FILENAME
Format string: $regexp(%_filename%,- \d+ ,- )
Sorry for my bad english...
I would try to explain better what i want to do.
In the uploaded photo you see the title in yellow. Well, what I want to do is:
Name of the file Artist Title
Tropkillaz - 1 Hideho.mp3 Tropkillaz 1 Hideho
I want to be like this:
Name of the file Artist Title
Tropkillaz - 1 Hideho.mp3 Tropkillaz Hideho
Delete the 1 and the white space only in the title.
I hope you can understand me better now 
Thank you for the help.
How often do you have to repeat this process?
If it is only once or up to ten times or so, then remove the number and space character manually, and the work is done.
If needed, then recreate the filename using the content from the tag-fields.
Other proposal:
Convert "Tag - Tag"
Field: TITLE
Formatstring: $regexp(%TITLE%,'^\d+\s',)
from: '1 Hideho'
to: 'Hideho'
Other proposal:
Convert "Tag - Tag"
Field: TITLE
Formatstring: $trim($trimLeft(%TITLE%,'0123456789'))
from: '1 Hideho'
to: 'Hideho'
