TI-Nspire OS installation files are PKZIP archives. They include several useless big files which will reduce your TI-Nspire free space:

• boot2.img and boot2.cer: a Boot2 image between 1 and 1.5MB useful for the Boot2 update (meaning useful 1 time in your TI-Nspire life...)
• samples.zip: sample documents in 15 different versions between 1 and 2MB (one version for each Nspire supported language, although you'll probably won't be using more than 3 languages - only useful the first times you turn on your TI-Nspire in your life)

Levak had allready released the computer tool TNOC which let you remove those useless files from your TI-Nspire OS installation file.

But you needed a computer, you needed to install the modified file, and you needed to redo this for each OS installation/update on your handheld...



Now here comes my new Ndless 3.1 program: nTNOC!
It does the same thing as TNOC, but directly on the calculator!

It automatically determines and removes useless files from the installed Nspire OS file.



Did you upgrade to 3.2 ?
Just downgrade to 3.1 and you'll get an additional 2MB free space!
Then install Ndless 3.1, launch nTNOC and you'll get another 3MB additional free space!
You're not dreaming: you can gain up to 5MB!


On TI-Nspire ClickPad and TouchPad with a 32MB chip and 27.8MB usable, it's awesome!



Do you think it's useless on TI-Nspire CX with the 128MB chip and 115.2MB usable?
I don't
5 MB more mean:

• dozens of additional PNG images for mViewer
• dozens of additional Game Boy, Game Boy Color or NES ROMs
• 1 to 5 additional Game Boy Advance ROMs

If you often install / update / remove OS 3.1 or Ndless, you can also put nTNOC in the Ndless startup folder, so that it will clean up the freshly installed/updated OS automatically and silently at boot time if necessary.





But there is another wonder with nTNOC...

Up to now, you couldn't send an OS from an Ndlessed calculator, although it was working when I was testing the alpha versions. The remove calculator just refuses the received Ndlessed OS.

Guess what?
If you use nTNOC with your Ndlessed OS, you can then transfer it between calculators without any problem!
Meaning that you can now install Ndless without the need of a computer - which should healp spreading Ndless more widely in the world!

It seems that the Ndless 3.1 installer has a little bug with a bad offset/size value written when it patches the OS PKZIP archive, and that nTNOC just fixes it

Wow that is awesome . I'll most likely put it on my calc once I play some Nspire games again. I don't think my OS 3.1 install is TNOC'ed.

Also I see OSes are starting to grow in size again.

Yeah I kinda worry they'll do so eventually, since those OSes will eventually no longer fit.

This will probably com in handy, I don't have much space left with all my Pokémon Games, good job, thank you!

Great news!  This is a very useful tool!

That's really great! nTNOS is a lot more convenient than the normal TNOS. 5 MB on a calculator (any calculator) is a lot!

You, sir, have just made my day. And since it's 12:22 AM, I'm going to be ecstatic for 11 hours and 38 minutes.

You go to bed at noon?

O.o? I just gained an extra 10mb, hopefully this is real
