I feel foolish to even have to ask this question but I don't want to waste a sizeable number of CDRs so here goes. I admittedly am confused by the many file formats involved in writing to CDs and DVDs. I just created initial images of my two computers using the latest build of TI 8 and now I want to put the 20 image files on CDs so I can delete them from the computers. I use Nero Express 6 for my CD burning and when Nero creates image files they come out as a .nrg format and I save them to CD using the "Make Data CD" function in Nero. Can I safely assume that if I save all the Acronis .tib files in this way that I will be able to use them to restore my systems if I need to? I don't know of any way to test the process so I need for someone who has done this to give me some assurance that I'm going in the right direction. Thanks in advance.
