SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

Thanks for clarifying.
Looks like the error message was wrong.
On windows ntfs I had a file name more than 259 characters which is widows limit.
After cutting file name to 259 characters everything works as it should.
If I cut file name to 260 characters I get the error from subject which is wrong.

Anyway case closed, thank you very much because I was suspecting that something is wrong with configparser.

Best regards.
