Thank a lot it,s really goood tool. Can anyone help me in renaming tool i need In this filename [img_****] @Bilou_Gateux I tried this method with my Win2000 install. I used the exact syntax you suggested (copy & paste) and it doesn't work. The only thing unclear is if I had to copy reg.exe to System32 to use your method... because I didn't! Where do you get this reg.exe version 2.0 from?
