Huge ISO file dimension compared to Nero


Recommended Posts

Hello,

I am having problems with creating an ISO file out of a folder with about 36000 files in 400 folders (yes, many of them are small).

Total size of files is around 636 MB.

Nero produces an ISO file of 690MB that fits a 700MB.

CDBurner XP (latest version) produces instead a 767MB ISO file that obviously fails burning into a 700MB CD.

Am I missing some settings?

Thanks,

Mario

Thanks.

File system settings was ISO/UDF/Joliet. Just setting ISO/Joliet and updating the disc, estimation went from around 749 MB to 675MB.

Couldn't imagine UDF could bring to such overhead - is it needed in any way for conventional Data CD's?
