Games do load files, but I suppose you mean that you never transfer files for
use with non-identical software, and therefore compatibility of the files
they read and/or write with other similar programs is not an issue. I'd just
like to point out that all of these kinds of programs are typically the same
way:
- Calculator applications
- Clock/alarm applications
- File managers
- Terminal emulators
- Device firmware
- Device drivers
I don't think compatibility, in any sense, is a particularly helpful
criterion to look at when determining how good or bad a program being
proprietary is.
