Thanks again i tryed with deleted files, and seem that everything working fine (all editions are installed fine), but still, i want to be sure what is behind this catalog files and i read that contain some informations, and ways of accessing to wim (admin rights, etc.) and i don't know how is important to installation. Anyway in same document i read that if wim modified (which is my case) all clg need to be recreated via WSIM as you mentioned.

Wow. This is amazing Thanks so Much btw about *.clg, what if i have both versions (x86, x64) same edition for example Professional? @grabben, as i understood, ricktendo64, you need to aslo keep Boot and Efi folders on root.

I already use maximum compression with Gimagex. But i just need around ~70mb to fit it to DVD5. I already look to delete Support and Upgrade folders which are ~67mb.

Ok i do some AIO DVD with Starter, Home Basic and Proffesional, because i have that 3 licences. I update it with hotfixes and programs for my needs. After integrating size of resulting dvd is 4.5GB which is oversized by little for DVD5. Can i delete some folder on DVD which will not affect Clean install or upgrade, like on XP can deleted everything except I386? Thanks
