Yo, I got this problem with my .001,.001,etc. files and WinRAR.
Well, the problem is that I downloaded 15 files, thats all there were. Then I opened up WinRAR, found the folder with the files, then hit the Extract To button. Well, it did its job up to extracting 15 files, but thwn it said I needed another file, that I needed .016, and there isnt one. What do I need to do, help me out, and let me know. Thanks...
