Hello Igor,

the 2 gig limit can be passed by using jfs.

The file system does allow file  >  2 GB..

The next step is, to verify , if the OS/2 port does support files  > 2
GB.

All the application you want to use with - requires the feature "> 2 GB
file support".  

This is theoretical knowledge,  I  have not worked with file  > 2 GB jet
:-)..

kind regards
