>Googling stuff I found out how to change ownership and modify both _default.pif (for XMS) and config.nt (for files) in safe mode. I found 2 copies each and modified them as usual. In config.nt I have tried files=150 (as always upto XP) and also tried files=200 but no joy I still get the Too Many Files Open error for the application.

You may need to remove the read-only attribute from the config.nt file.

Another approach would be to copy the default system config.nt file and create a custom one for your application, in some other folder. IIRC with earlier versions of Windows you could, in a .PIF file, specify a CONFIG.NT file to be used when starting an application.
