I've been storing my data on DVD's... well everyone does that. Anyway, I've been using a program called WinArchiver because it stores the Archives contents on every disc and it lets me use every last byte on the DVD's (4,699,815,936 for DVD+R) when I store a ton of data. Say I store 50GB of data, I'll turn it into a Split WinArchive format. I can load any DVD in the set and know the full contents of the entire archive without needing all the other parts in the same location. If I extract a file and it isn't in the currently opened part, it'll tell me what part it's on and prompt for me to load it. Now for my question. Is there a container format that I can use that will do what I can do with WinArchiver but let me specify the archive size per split. 7z can specify the archive parts individually, but it can only load an Archive if all the pieces are available. WinRar will only list what is in current piece if the other parts aren't available. I think Zip can do it, but I haven't looked into it yet. So any thoughts? Has anyone tried doing this before and what conclusions did you arrive at?
