To open a file on the TI-Nspire, you must be in the My Documents view. Simply highlight a specific file and press [ENTER] or [CLICK]. You can also highlight a file and press [MENU]→Open (or [CTRL][O]). The first page of the new document is displayed. To go back to the My Documents view, press [ON]→My Documents.
In the My Documents view, open files are designated by an asterisk symbol (*) to the left of the filename.
You have many ways to close a file on the TI-Nspire. Press [DOC]→File→Close (or press [CTRL][W]). Alternatively, [CLICK] the X in the upper-right corner of the screen. On the TI-Nspire Handheld, you cannot have two files open simultaneously.
Therefore, one way to close a file is to open another file. If you made any changes to a file, you are prompted to save the currently open file before the new file opens.
As for saving files, here’s how it works. A new document is not saved — it resides in TI-Nspire’s local memory, just like a new (but unsaved) document on a computer. To save a new, unnamed document, follow these steps:
Press [DOC]→File→Save to open the Save As dialog box.
By default, the cursor is located in the File Name field. Type the filename.
To specify a different folder location, press [SHIFT][TAB] to move up to the Save In field. Press [CLICK] to reveal and select an available folder or press [SHIFT][TAB] again and [CLICK] to create a new folder and type the folder name.
At any time, press [ENTER] to put your choices into effect and close the dialog box. Alternatively, press [TAB] until the OK or Cancel button is highlighted and press [ENTER].
To save a previously saved document with the current name, press [CTRL][S] (or press [DOC]→File→Save).
To save an open file under a different name (thus preserving the original file), press [DOC]→File→Save As.
