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 (http://tiplanet.org/forum/viewtopic.php?t=7918) 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! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

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! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)
Then install Ndless 3.1, launch nTNOC and you'll get another 3MB additional free space! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)
You're not dreaming: you can gain up to 5MB! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)
On TI-Nspire ClickPad and TouchPad with a 32MB chip and 27.8MB usable, it's awesome! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

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 ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)
- dozens of additional Game Boy, Game Boy Color or NES ROMs ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)
- 1 to 5 additional Game Boy Advance ROMs ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

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. ;D
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? :P
If you use nTNOC with your Ndlessed OS, you can then transfer it between calculators without any problem! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)
Meaning that you can now install Ndless without the need of a computer - which should healp spreading Ndless more widely in the world! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)
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 ;)
