compressed zip files apparently. Whomever uploaded them didn't do it
right, I'd say.

You're right, Don, those are ZIP files compressed with the standard (08)
compression format - but they are perfectly valid TNS documents
nevertheless ;)
08-compressed files are suitable for OS versions which understand this
clear-binary format, i.e. 1.1-2.1.0.631 (maybe 2.1.1.38 as well).
In OS 3.x, TI removed backwards compatibility with those clear-binary
files. OS 3.x versions flat out refuse to open these valid files, they
understand only the DES-encrypted files compatible with OS 1.2-2.1.0.631
(and again, maybe 2.1.1.38), noted by the proprietary 0D compression format.
It follows from the above that in order to be able to open these files
on newer OS versions, one needs to open them with OS 1.2-2.1 and re-save
them.
If you have already installed OS 3.0.2, and thereby made your calculator
unable to downgrade to any older OS version (in the current state of
things - and stripping the boot2 3.x through TNOC doesn't help), you
need the computer software.
If you wish, in the process, you may blame TI out loud for this
user-impacting move.
Lionel.

If TNS files are created from Lua scripts using non-TI products, do not expect miracles.
A Lua script written for TI-Nspire can be converted to a TI-Nspire app/page using TI’s Scripting Tools program available from the NspireScripting website posted earlier. And… the code must conform to TI’s scripting protocols.

was found by reverse-engineering ;)
It predates any release of documentation and tools by TI, which itself
shortly follows the involuntary leak of said documentation and tools on
the site of a third-party.

have, or can run, TINCS, which is required by TI's tool ;)
Jimmy, have you tried opening these files with OS 3.0.1, and re-save them ?

Here's a breakdown of the files you posted to the tinspire group. I was
able to convert 8 out of 10.
* atibank, cube, ico_sphere, Klein and tore: converted without a hitch.
However, they look like files suitable for the Ndless versions of
Make3D, so you won't be able to use them anyway.
* 15puzzle, FallDown and Puissance4: converted without a hitch. They're
known third-party Lua script files.
* Puzzle: not converted, because it's a Ndless program. Ndless 3.0, if
and when it is released, might read it, but it's not guaranteed.
* chembalance2: not converted.
Where did you get that alien file ?? This is a Lua script wrapped into a
document whose parts are both compressed with the standard 08 DEFLATE
method, so:
* OS 3.0.x reject it because the Document.xml part is not compressed
with the proprietary 0D scheme;
* OS 1.7.2741, which understands files compressed with the 08 method,
but not Lua, strips out the Lua script.
