1. Downloading the UDFs files

The UDFs files for General Maths, Math Methods and Specialist Maths are found in the 'Download' section of the website.

Click on the files you wish to download, these should then be downloaded as zip folders onto your computer.

2. Extracting the UDF files

The zip-folder(s) should now be in the 'Downloads' section of your file explorer.

Right click on the zip-file, then select the 'Extract All...' option

A window displaying the path of where the files will be extracted to will now show up.

Click on browse to change the path/location of where the files are extracted.

Find the TiNspire CX folder on your computer, its location will depend on where you set it up.

Afterwards, double click onto it to get into the folder.

You should now see a folder called 'MyLib' inside the folder.

Click onto the 'MyLib' folder then press 'select folder', then press 'extract' to move the folder into the 'MyLib' folder.

A folder titled 'MM3&4_UDFs' should now be in your 'MyLib' folder.
