DVD-R size

Why when I try to write a file of 4.6gig to a 4.7gig does Copy to DVD tell me the file is too big for the destination disc?

Cause it actaully is not 4.7gb for video DVD I believe....All my software only allows me no more then 4.5gb of filesize (vobs and ifo files) to fit on a standard dvd-r disk and that is built into at least 3 of my burning software I have...

I haven't tested to see if a data DVD will allow closer to the 4.7gb but I think the extra stuff that may have to be written to the DVD for it to work in standard dvd players may take up some of that space...

Basically I don't know the exact reason for it just the fact I know it can't do it....

4700000000 bytes = < 4.4 GB

It turns out to be 4.37GB is the amount of the Data you can fit on a DVD-R.

Even just plain old file backups?If this is true then why in the hell aren't they labeled as such

I guess you didn't read my other post.

Companies like to put these fancy high number of gigs (in the past it was megs) that are 1000 of the next lowest measurment. I.E. one gig is 1000megs, 1 meg is 1000 kb, one kb is 1000 bites, and I think one bite is 8 bits, although I am not sure,

Anyway, you should know that EVERYTHING in the computer world is a power of two. Yesssss. 1000 is not a power of two, but 1024 is. So a REAL kb is 1024 bites. A real mb is 1024 kb. A real gig is 1024 mb, and so forth.


Its called marketing.
