Generally with a multi-part compressed file, all files should be in one directory. If you got only one file in your directory, you are probably missing one or more files. They'll be one "master" file, and one or more "chunks", for lack of better names. For PKZIP / WinZip, the master file will have a "zip" extension, and the chunk files will be "z01", "z02", ... They should all be in one directory. In every case I've seen you start (double-click) the "master" file. It knows it's a multi-part file, and will automatically look for the related chunks in the same directory. If it's a multi-part file, and it can't find it's related "chunk" files, it generally will give you an error message. You can force it to go ahead usually, but you'll be missing files.
