UDF image size vs file size

[shar]

I'm burning DVD/DVD DL discs using UDF and I'd like to max out the disc with recovery data using Reed-Solomon error correction.

 

I wanted to program a disc calulator that could take the file size and compute the image size and determine how many bytes I can allocate for the recovery data. (yes, I'm that bored that I truely want to max out the disc, and not just leave a 2mb cushion space).

 

So my question is does anyone know how to compute the image size based off the file size, or point me to where I can read how do it?

 

Thanks...

You need to work out the overhead for the filesystem... I'm not sure it's an easy thing to do without actually creating the file system!

 

ImgBurn's Build mode works that way when you press the 'Calculate' button.

 

I think you might be better off just adding a field where you can type in the info from ImgBurn.
