Any file splitter can split files. That has been around for years. But this splitting must have more going on than you asked for.
Be aware you are on a CBS (yes, that network) forum so be careful as we can never discuss ripping of DRM content and all my BDs are DRM'd.
Ok guys i am wanting to split my blu ray rips (m2ts) that are larger than 25gb. Is there software designed to split them into separate files? I have tsmuxer but am unsure on how to do it. I was told that i can with that software. Please help!
