Thank you, I even found out what a UTI is supposed to be.
http://developer.apple.com/documentation/Carbon/Conceptual/understanding_utis/understand_utis_conc/chapter_2_section_2.html
But e.g. an InDesign document gives me a dynamical UTI like 
"dyn.ah62d4rv4ge80w5xequ" instead of something reckognizable like 
"IDd4" or "application/x-indesign".
OpenOffice documents give nice UTIs like "org.oasis- 
open.opendocument.spreadsheet", but some widespread formats like RTF 
and PDF just give nothing at all!
Very strange.
Could you please tell my how I apply the "OSType" method to an UTI?
Something like LaunchServices.UTType.UTGetOSTypeFromString(UTI) ?
