Whenever you wish to split a movie file into smaller pieces so that it can either be transferred to an external device or burned to a disc, the first thing you have to do is have the file stored on your computer. Then, you will need to use a special software program to split the file.

After you’ve transferred the file to your computer, you can use the many different software programs that are available as a means of splitting the file. If you don’t have one of these programs, you’ll have to download or purchase one either from a software retailer or an online distributor. Without the program, you won’t be able to manage the file more than to play it on your computer.
The exact program you are going to need is going to depend on what format the movie files are in, but one example of a program you can use for free is called Free Video Converter by Extensoft and is available for download at CNET.com.
Once you have a functioning media file managing software installed on your computer, you’ll have to open the program and import the file from your hard drive into the program.
After you have imported the file to the program you’ll be able to view it, decide the points at which you’d like to “cut” it, and finalize the action that splits the file from one into two or even three different files, allowing you to burn each file onto a disc.
