Do you have ANY information other than the file extensions? Was this a general purpose database? or, was the program a special purpose program which stores its data in files with the above naming convention?

Was it a mainframe app?

Hello, thanks for your attention to my problem!
This database is used by a legacy application who is programmed (i think...) in visual basic.. the application is composed of 100-120 files .exe (one every program function).

Before it's ported to VB with windows interface, this apps is born to be used in dos.

Many thanks!

It sounds like it's a custom format of some sort. Have you tried opening the files with notepad to see if it's a fixed width format?
