Why does a file created by PowerVCRII 3.0 have the extension "plt"?

"plt" means "Playlist". Because of the inherent issue of the Windows operating system handling files over 2GB, PowerVCR II will automatically save and chunk your video files into 600MB files if the file!|s size crosses this limit. However, when you select the appropriate playlist for playback, all the files are played continuously leaving you worry-free from video file sizes and constraints.
