Things You'll Need
Instructions
Open your Web browser and navigate to the download page for your preferred file-splitting program. If you do not know which program to use, a number of download links have been provided for you in the Resources section of this article.
Download and install the file-splitting program onto your computer's hard drive.
Launch the file-splitting program.
Select the "Split a file" option--this option may appear as a button or as a tab, depending on your program of choice. From there, click the "browse for file" button and select the PS2 ISO on your hard drive. Click "OK" to return to the file-splitter program.
Type in the size of the files you wish to split the ISO into--it may also be necessary to select "custom size" from a drop-down menu, depending on your program. Once you have selected the appropriate size, press the "Start" button, and the program will split the ISO into several equal-sized parts.
