More free space on your TI-Nspire with nCleaner and Ndless 3.6
本帖最后由 critor 于 2014-3-19 21:57 编辑In a previous news, on the occasion of the release of the OS (Operating System) 3.6 for TI-Nspire, we were exposing a small history of TI-Nspire OS sizes and of the space which could be gained for each one by using the TNOC utility.
Indeed, the OS installation file size has been increasing year after year, and now stands from 9.6 to 11.8 MB depending on the TI-Nspire model targetted by the 3.6 version.
However, be aware that the installation file of the OS is recorded and stored as such on the calculator in the hidden path "/phoenix/install/TI-Nspire.tnc".
Our TNOC utility principle was thus to lighten the OS installation file a little by removing some unnecessary entries, including:
[*]the image of the Boot2 (used only for an update that might be performed only once in the life of the calculator)
[*]sample files (will not be helpful to some new users )
This was enough to save several megabytes :
Alas, with OS 3.6 for TI- Nspire, Texas Instruments decided to put an end to this practice. The installation file now includes a complete list of resources that it is supposed to include, and the OS will check that list once installed and launched. If any item is missing or corrupted, the OS starts the uninstall process immediately.{:thumbdown:}
The capacity of the TI-Nspire file system is:
[*]27.8 MB for the TI- Nspire monochrome
[*]115.2 MB for the TI- Nspire CX
However, if you subtract the OS installation file size to it, you will notice that you don't get that much free space after installing the OS an empty calculator at all. :o
Indeed, it turns out that during installation of the OS, some of the resources contained in "/phoenix/install/TI-Nspire.tnc" are extracted to the file system.
Which brings us to another method of optimizing space since we can not alter the OS installation file anymore: cut in the extracted resources! ;)
Thanks to the release of Ndless 3.6 last weekend, it is now possible to use the nCleaner utility on OS 3.6.
nCleaner looks for unnecessary resources in the file system, and tells you in each case how much free space their removal is going to bring.
Among these resources are:
[*]a 1.5 MB image of the archive memory of a TI-84+SE on monochrome TI-Nspire non-CAS, useless if you do not use the TI-84 keyboard removable
[*]big vectorial skins the calculator, having nothing to do here since no screen or menu displays them
[*]data for the 14 to 15 languages of thecalculator
Among these resources you can remove all of them without danger, and except for the TI-84 + SE archive on monochrome TI-Nspire non-CAS calculators without any loss of functionality ! {:thumbsup:}
Yes indeed, remove language resource files doesn't prevent from using the matching language at all, as the OS can directly load those ressources from the "/phoenix/install/TI-Nspire.tnc" file.{:biggrin:}
With nCleaner Ndless 3.6 and then you can earn up to 1.3 to 2.9 MB of free space on your TI-Nspire running OS 3.6.
So your calculator can reach free space capacities that you dared not even dream of with this latest OS . :D
Even if the gain can be considered negligible on the TI-Nspire CX with their 115.2 MB storage capacity, on the TI-Nspire monochrome with their 27.8 MB to which you have to substract the OS installation file size is quite useful for some additional PDF documents ;)
