Hello guys,
how to change only some information in multiple files at once?
For example here as you can see in picture the songs name start with A1. - and name of the song
I want to replace only the sign A1. and B1. on all songs with the name of the artist but keep name of the song at once. How do it please?
Thank you.

You have to select the songs you want change, for example the five tracks from A1 to A5.
Then the steps depend on what you want to do:
a) Do you want to remove "A1." until "A5."?
b) Do you want to replace A1 with something like 1 or 01, A2 with 2 or 02 and so on?
c) What do you want to do with B1 to B5? Replace it with 6 or 06 to 10?
We can tell you the needed steps if you show us the desired result for your tracks in a example.
You can also have a look at this documentation:

I want replace A1 - A5 for Cleveland Robinson also B1 - B5 but keep the songs name.
Example:
A1. I Got Yours, You Got Mine - should be Cleveland Robinson - I Got Yours, You Got Mine.
A2. No One Can Take Your Place - shlould be Cleveland Robinson - No One Can Take Your Place
And that i want for all song, so basically put the name of the artist before the songs name, but for all songs at once.

In your case the steps are:
a) Select all 10 tracks
b) Click on Convert Tag -\> Filename
c) Type this Format string:
`%artist% - %title%`
and see if the immediate preview shows the expected result
d) Press the OK Button.
Please note:
Without a track number in front of your tracks you can no more play the tracks in the original sort order. Especially for classical music or audiobooks this is rarely desirable.
