Hi everyone and thanks in advance for your help!

 

I have a MBP running Mac OS X 10.7.5. I downloaded a .iso file. The site which I downloaded the file from says the file is 4.31GB, which should fit on a regular single layer DVD-R, which, afaik, can store up to 4.37GB. My torrent client says the file is 4.3GB. However, when I "get info" for the file, it says that it's 4.63GB on disk. When I try to burn on a single layer DVD-R, my MBP says I need a larger DVD-R.

 

Why is the file size larger on my HD than it should?

 

Same thing happens with .avi files. I have downloaded several .avi files that are around 700MB in size, but my HD views them around 740MB instead, which renders them unburnable on a regular CD-R.

 

Any help?

 

Thanks!
