Also, 2. how does ttpack differ from ttppggen? I heard that both generated "exe-packed executables" And Finally, 3. can a calculator actually execute and use packed or archived variables generated by the Tools Suite? I mean like, it doesn't really say in the docs w/ Tools Suite... $:\$

The ones you quoted are decompression/unarchiving programs. Their counterparts without the "un" are compression/archiving programs. *Quote:* 1b. what do they do? ttarchive groups programs without compressing them, and ttpack compresses programs without grouping them. *Quote:* 2. how does ttpack differ from ttppggen? I heard that both generated "exe-packed executables" ttpack is used by ttppggen, as are ttstrip, ttpack and ttbin2oth. ttppggen is just a shortcut automating the unwrapping, compressing and rewrapping steps for executables. *Quote:* 3. can a calculator actually execute and use packed or archived variables generated by the Tools Suite? No. For ttppggen, ttpack or pstarter is used to run those programs. For the others, it's the responsibility of the program using the data to unarchive and/or decompress it.

For the ttpack and ttarchive functions, it sounds like functions from Flib libray... Have you ever used it? Flib Link In Flib, it sounds like functions komp and group Anyways, for ttpack, should the compressed variable have the same extension as the variable compressed? But in the resulting ttpack file, since it doesn't begin with TI89 or something like that, it can't be sent to a calc, can it?

Creating a ttarchive would in principle be possible on-calc, but the code hasn't been ported because that's not what it's intended for. ttpack compression uses way too much memory to run on-calc.

If I understand correctly, both the output files from ttpack and ttarchive can be un-packed (or) un-archived on a calc. But then how can you do that? Do you use some program to unpack and/or unarchive? 2. This leads to a new question (I hope Im not getting annoying with all these questions) I heard that there could be ZIP and EXE files on a calc (some file managers claim to have EXE and/or ZIP support) How can you make a calculator ZIP file or EXE file? (sorry if Im getting a little bit off topic here, but this seems to be the only place where someone can help me)

The routines are usually embedded in a program, like the launchers generated by TIGCC for the compressed programs, or their generic version ttstart, or SuperStart. Decompression is temporary. IIRC, TICT eBooks (ttebkgen) are TTArchives.
