Thanks for your time and investigating for my problem. After all I have found out what was my problem. It was not CLRMAMEPRO and not the uploaded XML-File. The initial issue was triggered by a datfile that was missing the information regarding the empty nes, sg1000 and sc3000 folders. After creating the set with this datfile and checking with a profile created with the mame.exe within CMP, it wanted to move the files mentioned. Because I had disabled "Sets' while scanning, the information in the scan results was missing the information that the ROMs were merged to the correct folders ......
About the t7z problem: seems that 7z 9.38 beta has a bug. With 9.20 it does work.
