those multi part files are more then likely rar files. u need winrar to extract the movie out of the multi part dl. If so it will look like this whatever movie.rar .01 .02 ect. ect. or whatever movie.part00 .part01 ect ect open the .rar or part.00 file with winrar and you will see the movie u dled inside drag the file out and drop where u want the movie phone storage card or folder on your pc. After the extraction is done then u can close win rar and delete the milti part files as you won't need them anymore.

The reason this is done is the file sizes are large and win rar can compress better then standard zip compression saving download time. The other reason it is popular is say something goes wrong with the download and a file gets corrupted all u need to re download is the messed up part, not the whole file, again saving time and bandwith.
