Using all 4.7GB of a DVD

Most likely that there is a simple answer to this.

I have a bunch of files which total 4.44gb (4,773,531,648 bytes)

If using nero (only software I have)
Says there is only 4500mb free on the disk.

Am i missing something here?

Dont want to use another dvd just for a few files!

 

4.45GB = 4552.39MB = 4661652KB

If you have 4500MB free, then there's not enough room for 'em all.

 

basically it's the same reason hard drives report as smaller than the packaging says.

manufacturer says one kilo = 1000, one mega = 1,000,000, etc. so to them 4.7gb = 4,700,000,000 bytes.

but in compuspeak it's all powers of two, so divide that by 1024 = 4589843.75 kB. div that through by 1024 again, and you have 4482.269287109375 actual megabytes.

 

That's because a computer normally reads in GibiBytes, MibiBytes, KibiBytes and so on.

GiB, MiB, KiB

 

And I have a A level in computing, forgot about that

Thanks lol

 

Pretty much as above, storage is measured in powers to the ten (10ⁿ) while things like memory (RAM) and OSs measure in powers to the two (2ⁿ).
