Not sure if I got the Screen Thief fix in, but I fixed up the progress bar and the renaming of short names. I made a bunch of UI changes including adding the file browser and text viewer. Version 1.4 attached to the original post.

One thing I haven't addressed is when trying to view a text file that's inside an archive within an archive. XArc wants to extract instead.

Oh, believe it or not, i'm well aware that we've not been talking about DOS conventional memory. Wether or not you consider XMS as part of DOS (it's an add-ons shipped with DOS) is a matter of opinion (I don't particularly - but many people disagree) - but even with "normal" XMS you can'y go beyond 4G (and even >2G is tough) [...]

Fair point. I'm personally in the camp that believes DOS is nothing more than IO.SYS, MSDOS.SYS, and COMMAND.COM (or IBMIO.COM, IBMDOS.COM, and COMMAND.COM for PC DOS). Everything else bundled together is just an optional, extra utility not required for DOS to operate.
