so i have .zip, .001, .002, .003 files. apparently its a movie that couldnt be uploaded in one piece. how do i unzip these files? when dragging the .zip to stuffit expander i get the error "does not appear to be compressed or encoded" i downloaded the program MacHacha, which combined the .001, .002, and .003 files together, forming one file. however, i still coulnt unzip that. meanwhile i still had the original .zip sitting there, uncombined. i even went to terminal, and typed unzip filename.zip this gives me the error of "cannot find the .zip" which doesnt make any sense because not only did i point the .zip out, i asked it to unzip it. whats it looking for?! does anyone have any idea how i would join and unzip these files?
