In a previous news, we released nTNOC, a wonderful tool to clean up your TI-Nspire OS main file (/phoenix/install/TI-Nspire.tnc) and gain 3MB on your TI-Nspire, and even 5MB if you were downgrading from OS 3.2.


But there are other useless things we can clean up on the TI-Nspire, like the hidden system folders extracted when you install a new OS.





For example, on non-CAS TI-Nspire and TI-Nspire TouchPad, there's a 1.5MB backup for the TI-84+SE emulator.

It does include all preinstalled apps.
If you don't use that emulator, if you don't even own the special removable keypad necessary to launch it (not included with the TI-Nspire TouchPad), or if you just don't care about the preinstalled apps, then that's useless!



Big surprise, the filesystem does also include two TI-Nspire software skins taking something like 275KB!

Those are the SVG image files used on the TI-Nspire Computer softwares, and they're totally useless on the TI-Nspire handheld.



You also get data for the 15 supported languages in many subfolders, especially for the chinese languages.

If you don't speak 15 languages then again...



And you also get the OS extensions (the only one released up to now is the chinese-english dictionnary) which cannot be removed officially.





Anyway, the problem is now solved this evening, thanks to the new tool by RayQuaza59 and myself: nCleaner!

You just have to choose what you want to remove:




But wait, that's not all...

Even after removing the TI-84+SE backup, you can still use the TI-84+SE emulator.
It will just start with an empty memory, and recreate the 1.5MB backup once you turn off your handheld.

Even after removing all 15 languages locales, you can still set your OS in all 15 languages!
Yes, I tried everyting... rebooting and all... those files are just useless, maybe only needed by the TI-Nspire softwares, included and extracted by mistake from the OS file like the skins.



Using nCleaner, you can free up to 6.5MB!


You get even more free space by using nCleaner together with nTNOC!




You can get as much as:

• 20MB free space on non-CAS TI-Nspire
• 20.6MB on TI-Nspire CAS
• 108MB on non-CAS TI-Nspire CX
• 107.7MB on TI-Nspire CX CAS

Do you often reinstall the OS?
Of course, this is going to recreate all useless files...

But nCleaner does remember your settings, and can even clean up everything automatically and silently if moved to the Ndless startup folder.

Can it cause crashes if I try to select a missing language or will it just exclude it from the list automatically?

If a non-null size is displayed on the right, then nCleaner found files/folders to remove.

If you remove everything and relaunch nCleaner, all sizes should have dropped to zero.
There is just nothing left to remove and it won't crash trying to remove "nothing", no.

Oh I meant, for example, if in the TI-Nspire menus, after deleting the French language files, I decided to select French again. Will it cause strange errors about missing files or even crashes? I know certain Windows apps like RPG Maker will crash or cause errors if you try to run a game or edit a game after deleting its chipset, for example.

Hmm interesting. One thing I wonder is if the languages can be removed entirely. Unless the OS can't be modified at all?

Yeah that's the amazing part, and also the fact you can remove around 3 MB or more

I still use OS 3.1 on both my calcs I think, so this tool will be much needed when I install new ROMs.

wow, this is awesome on one hand but on the other hand it makes TI even more stupid.
Kinda glad I don't have a nspire

Alright, from now on no more useless stuff on my nspire. Good job 

P.S. How do you get to browse the system files from the normal documents screen 

[edit] I especially like the quite huge free space increase for clickpad models (but what's up with the clickpad CAS gaining more free memory then the NON-CAS, or am I misunderstanding the diagram?)
