I agree with CBC and MTC, because this was the reason for the mistake i postet before. I just thought "creating an iso" would be the last step (logical it is) and so i did not use the reduce option given at the end. Expecting a great reduction of my Xp Files, i was wondering, that the Image still had 512 MB 1 More Problem is, that there is no hint, that reducing the files is a seperate function. I just thought it is automatically done when creating the iso. I did not expect to find that option under "custom file List". I thought, this is just possibility to choose some extra files beeing removed, the programm does not offer.
