Problems with JXFS, note for OS4 developers

Hi everybody,

I had a problem with a behaviour of my unrar compilation.
I wanted to list and extract big archives.
I made some changes in the source and I didn't succeed to use it, i.e. I had a seek error when the file pointer was beyond the 2 Gb limit.

I tracked down the cause, it was the ftello64 function which returned to me a 32 bit int even I used a 46 bit integer.
I posted in UtilityBase but no reason to that.

The problem was that the bif unrar file was located on JXFS partition because when I put it in a SFS2, all was right and unrar worked perfectly.

I use JXFS file for all my downloads because of the possibility of using big files like dvd images.
I wanted to know more about this filesystem, what are the real differences with SFS2 ? I read the readme file of JXFS but not useful informations.

Even that is already written a lot, I would want to thank the Hyperion team for his job on this OS 4.1.
