File formats for CD and DVD Data

I was noticing on my data burning application there are choices for file format. I know what ISO and UDF are. Has anyone heard of USIUDF and InCDFS?

i believe iso and udf are image files where are usiudf and incdfs are filesystem types, like fat32 or ntfs

InCDFS is most likely a modified version of CDFS, that allows drag and drop. They are usually created by a host app called InCD, which I believe is part of Nero.

You have to "format" the CD before hand, and then you can use it just like a floppy disk. Modern drives support a feature called mount rainier, which IIRC does a similar job to creating an InCD disc in as much as it allows drag and drop without prior formatting, windows xp though I think just caches files before you write them, but I think older OSes would write directly to the disc.

As for USIUDF, I've never heard of it, but I assume it's the DVD (UDF) version of what I mentioned above.

And yes, CDFS and UDF are filesystems for optical media as FAT32 and NTFS are to hard drives.

ISO is an image file, you also get others such as BIN, CCD, NRG and MDF

ISO 9660, which is what video DVDs use is limited to 1.0 GB. That's why VOB files are the size they are. I suspect that's what the data program you are using is using.

UDF 1.0 has a 2 GB limit. UDF 1.5 and 2.0 have 4 GB limits, I think. What program are you using? Ulead's DVD Moviefactory and Burn.Now use both ISO and UDF.
