After split, only the first file plays rest are not viewable

Everytime I split a file, no matter which combination I use, the 2nd or 3rd or 4th file won’t play. THe orig file is 5 gigs and the first file, even at 3.6 gigs will play, but the 2nd file won’t play. I use BS Player, and I have a video file…thanks for your help…

thanks
Scott

Oh ya, I forgot, the 2nd file always says can’t find ‘codec’

From the doc at http://www.gdgsoft.com/gsplit/help/Getting_Started.htm:
Please keep in mind that GSplit is a generic file splitter: the piece files it creates are generally not meant to be used. For example, if you split a multimedia file (AVI, MP3, WMV, RM, OGG, MPG, MP4, FLV, etc…), the resulting piece files cannot be played! If you want to play your media file again, you first need to join the pieces back together using the Self-Uniting program or GUnite. The reason is simple: piece files do not contain the headers required by the media player so they are not recognized. GSplit is currently unable to add these headers because this would require handling a lot of different media formats.
