I have a large video file that I want to split up so I may put it on a cd. It is about 926mb. I tried to import it into iPhoto, but instead received a prompt telling me that there was not enough room on the hard drive to import it. I checked and I have 5gb left of free space. I dont know of any other way to do it. Or perhaps a program to compress the file, like a zip file. I dont know what the Winzip counterpart would be on a mac. Any ideas?
