I know that the FAQ indicates that UltraISO can handle .ISO files up to 2TB in size, but when you create an .ISO a media type appears to be associated with it.  The largest media type in the image properties dialog is 9.4GB (DVD dual-layer media).

When you create an .ISO file bigger than the 9.4GB the meter in the upper right of the GUI interface goes red indicating that you've exceeded the media size.  Does this mean that the .ISO will be invalid?

I've got an application where I'd like to use the .ISO as a container for virtual machines, as well as ancillary files associated with the virtual machine.  As you might imagine, the .ISO might get a bit large (>10GB).

If I create an image larger than the DVD dual-layer media will I have problems if I mount the .ISO and attempt to read it?   Do you know where the file-system support ends under Windows (as far as supported UDF image size)?

Can it be burned to a blue-ray disc and used that way?

Thanks in advance for your support.

No problem. ISO image is a logical volume which has no relation with media type.

Yes, I understand that the .ISO is a logical volume, but it usually has a file system contained within it, and that file system has media constraints (sector size, ECC, etc.,...), no?

Can a larger (>10GB) UDF .ISO image be written to a blu-ray disc and then have the disc recognized by a blu-ray file system?  Microsoft is getting ready to release their blu-ray file system soon, so I don't imagine that you've had a chance to test UltraISO images out on their file system yet (or have you???).  I'm not sure what other OS's have blu-ray file system support yet, but have you tried any out yet with UltraISO?

The reason I ask is I haven't yet seen any info up here on your site about blu-ray support (unless I missed it...;)...

Are you planning blu-ray support?

I was also wondering if support for blue-ray will be added.

I just logged on to check the same thing. I was wondering about both blu-ray and hd-dvd support.

It's been a few weeks since I've had a chance to check back at this forum for some answers.

I see some other folks have also inquired the same thing.

I also see that no reply was given to my last question.  Are we to assume that we cannot use UltraISO for Blu-Ray discs, or are we just "rabble-rousers" trying to spread viscious rumors about UltraISO's current limitations?   ???

Currently, these larger size media (DVD-DL and DVD-BD) are pricey, and I'd like to not waste any discs if possible.

Thanks for your continued support.

We're not just rabble-rousers, it's a legitimate question.  I'd assume that EZBSystems will probably add this feature as it will draw more customers to buy the product, but don't take my word for it.
