I'm not really good with computers, and I just wanted to see if this idea I had would work.

I have a lot of long videos (about 300mb or more) saved to my computer, and I'm starting to get worried about running out of memory on my laptop. But I do watch the videos a lot and I want to save them somehow. My idea was to save them to multiple discs, and then when I wanted to watch one, put the disc into my computer and open the file. My question is...will that work? (I'm sorry if this is a really stupid question, but I'm confused and people at this community have helped me before so I decided to try!) 

Thank you all in advance!
