Please forgive crossposting - I have asked this question in another forum and got NO response. I have a CSO file - I have no applications that can use this. I understand that it is a compressed ISO file. I would like to decompress it. How? Most discussions on this topic appear to centre around memory sticks and PSP's and ensuring that you have a Root folder called ISO - I dont care. I want an ISO that I can mount using Virtual CD 8 or that I can burn at my leisure. Help please..?
