This makes No sense to me. I have the following:
filename = 'maks'+strcompress(xx)+'.txt'
File1 = filepath(filename,subdirectory = ['Final'])
openw,lun,File1,/get_lun
then I get the error OPENW: Expression must be a scalar or 1 element array in this context: FILE1.
before even getting to the printf part.
thanks

This probably means that your variable XX is an array (possibly with one element). Try
filename = 'maks'+strcompress(xx[0])+'.txt'
File1 = filepath(filename,subdirectory = ['Final'])
openw,lun,File1,/get_lun
As a side note:
IDL> print, filepath('somefile',subdirectory = ['Final'])
/usr/local/exelis/idl82/Final/somefile
Are you sure you really want to write to the default IDL root directory? If not, you can do something like this:
IDL> root_dir = '/my/data/directory/'
IDL> print, filepath('somefile',subdirectory = ['Final'], root_dir=root_dir)
/my/data/directory/Final/somefile

The problem that you had is in the OPENW line. If you define file1 as you did, then file1 is an array (what is ok), but with OPENW you cannot open more than one file. You could also make it as:
filename = 'maks'+strcompress(xx)+'.txt'
File1 = filepath(filename,subdirectory = ['Final'])
openw,lun,File1[0],/get_lun
...
