TreePad BIZ (Business Edition) - this is la créme de la créme in the series! In addition to all the features found in TreePad PLUS + SAFE, this TreePad version offers thesaurus and spell-check in more than 20 languages, auto-dial, full-screen presentation mode, and a number of other real special goodies. It's a super program, really! Though it amazingly fits on a diskette, leaving room also for data files (like all other 's).
TreePad is in my Start-Up directory -- I would literally not know how to live without it by now.
The F1fan eBook that you are currently enjoying has been all written on TreePad BIZ, including the HTML version that is on-line: it was exported to web site in one go.
I have seen TreePad BIZ referred to as office-on-a-floppy (on some software download sites). And, yes, TreePad BIZ is just about an entire office, itself, so many its functions. To this I should just add that, when you take TreePad BIZ + your data somewhere, on a floppy, the spell check and thesaurus have to go on a separate diskette, if you need them: these files are just as large as the program, itself, covering over 20 languages, as they do.
