How do you use demosplicer? I was gonna do a segmented run of portal but I can’t even load demosplicer up ---

It’s a command line program so opening it directly won’t show anything. Once you have all your demos, make sure they’re in a folder with sequential numbers then from a command prompt or in a new .bat file in the same folder as the DemoSplicer.exe run `DemoSplicer.exe outputFilename.dem "D:\Path To\All The\demos"` And it’ll do it’s thing. ---

the problem is I can’t even load up the program to enter that. ---

What do you mean by “load up”. If you double click the exe it should just flash up a black window and close ---

Yeah, you’ll need to launch it with command line parameters, like: > [@Cameron\_D](#): > > from a command prompt or in a new .bat file in the same folder as the DemoSplicer.exe run > > `DemoSplicer.exe outputFilename.dem "D:\Path To\All The\demos"`
