Hi, I’m back…I think the problem is with no file extension. When I combine it creates a 5gb file. With no file extension. I tried adding “.7z.” Before and after combining. Doesn’t work. I tried “cat.” In terminal. It created a 10gb File. No file extension. I can’t extract. I tried “add to archive.” In 7zip. When I extract I get the same 5gb file with no file extension. The download says “xxxx.001.” Instead of “xxxx.7z.001.” So when I combine it creates a file with no file extension. Like “7z.” So how do I combine the files? Please reply. Thanks
