Is there a way to remove letters from the beggining of a file name?

If you wish to remove so many letter then yes... if you wish to remove certain letters, no... well, not easily. Please elaborate more.

You set a variable with the information you want to work with...

Then you can use the following:

%variable:~3%
%variable:~5,6%
%variable:~2,-7%
%variable:~-10,3%
%variable:~-15,-6%

First one will remove the first 3 characters
Second one will remove the first 5 characters and only display the next 6 characters
Third one will remove the first 2 characters and display everything but the last 7 characters
Forth one will be the last 10 characters but only display the first 3 characters of that set
Fifth one will be the last 15 characters but only display the last 6 characters of that set (kinda worthless, but works nonetheless...)
