Suppose I wanted to echo every executable inside the %programfiles% folder
cd %programfiles%
for /r . %i in (*.exe) do echo "%~i"
but it yields
c:\program files\program1\program1.exe
c:\program files\program2\program2.exe
and I want
program1\program1.exe
program2\program2.exe
How to remove those prefixes?

To edit a command, use the left and right arrow keys to move around and the Backspace key to delete characters. You can enter commands that span more than one line. Delete next word (to the right of the cursor).
However, if you are using a command file with the . cmd extension, Windows will think it is a command line script file and run it in the command line prompt. In this case, right-click the . cmd file and choose "Edit" or "Open with" or the Text Editor already associated with your command files in the popup menu.
2.2 Set/Unset/Change an Environment Variable for the "Current" CMD Session. To set (or change) a environment variable, use command " set varname=value ". There shall be no spaces before and after the '=' sign. To unset an environment variable, use " set varname= ", i.e., set it to an empty string.
Syntax SET variable SET variable=string SET "variable=string" SET "variable=" SET /A "variable=expression" SET /P variable=[promptString] SET " Key variable : A new or existing environment variable name e.g. _num string : A text string to assign to the variable.
You could use the string replace function of batch
pushd %programfiles%
set "prefix=%programfiles%"
setlocal DisableDelayedExpansion
for /r . %i in (*.exe) do (
set "progPath=%~i"
setlocal EnableDelayedExpansion
set "progPath=!progPath:%prefix%=!"
echo !progPath!
endlocal
)
