After a bug in the Open Watcom OS/2 resource compiler has been fixed (imagine that – they still fix bugs related to OS/2! 🤯💚), I was able to make some more progress with the OS/2 GUI version of my little disk usage tool. It now has a menu bar and a dialog to open another directory:

The video includes the ZMODEM transfer process of the 50 kB .EXE file from my laptop. It’s a bit lengthy, but I kept it in for nostalgia. 😅

Next up is probably multithreading: Do the disk scanning in a background thread so the UI doesn’t freeze. (This is running on a Compact Flash card, a real hard disk would be much slower.)
