I've been tempted by this, but I have some reservations:

1. Does it work under less-used OSs? Linux/BSD..?

2. Is it a proprietary format? Will you be able to open the file in a decade? My text files will be able to be opened, I'm not sure anyone can still open their MSWorks files.

Maybe I'm crazy to worry about opening these files after a decade since using them probably isn't worth while unless you keep up with it. However, I've got files from the 90's that I've been transitioning from machine-to-machine since storage costs keeps getting cheaper.
