An AROS port is possible. At this time I can't promise anything, but as far as I know, AROS' GUI system is similar to MUI, isn't it. I'll try to develop the code for file I/O in plain C (or maybe C++ cause classes are a nice way to implement such stuff), so it would be easy to port it. The only thing which would have to be rewritten would be the GUI part. As soon as the app is finished, I'll think about porting it. Btw. is the Installer available for AROS? Otherwise such a port wouldn't make sense.
