User folder: This is a folder created and named by you. You can make a user folder the current folder, move data to a user folder, etc. You can also delete and rename a user folder as required. You can have up to 87 user folders in main memory at one time.
Tip: You cannot put a folder inside of another folder.
Current Folder
The current folder is the folder where the data (excluding eActivity files) created by applications are stored and from which such data can be accessed. The initial default current folder is the “main” folder. You can also select a user folder you created as the current folder. For more information about how to do this, see “Variable
Manager operations” on page 30.
Using Variable Manager
Variable Manager is a tool for managing user variables, programs, user functions, and other types of data.
Though this section uses only the term “variables”, the explanations provided here also refer to the other types of data that can be managed by Variable Manager.
With Variable Manager you can:
• Create, delete, rename, lock, and unlock folders, and configure current folder settings.
• Delete, copy, rename, move, lock, unlock, search for variables, and view the contents of variables.
About Variable Types
A variable with a letter name like x and y can be a user-created user variable, a system variable, or a local variable.
• System variables are pre-defined reserved variables, and cannot be renamed. For the names of and detailed information about system variables, see the “System Variable Table” on page 299.
• A local variable is a variable that is temporarily created by a defining function, program, or other operation for a particular purpose. For more information about local variables, see the “Local” command under the “12-4
Program Command Reference”.

Selecting a Folder
• If no check box is selected on the folder list, any folder operation that is performed affects the folder whose name is currently highlighted on the list. If any folder check box is selected, only that folder is affected by a folder operation, and the folder whose name is highlighted on the list is not affected.
• Selecting the check box of a folder causes the check boxes of all of the variables inside of it also to become selected.
• When renaming a folder, only the folder whose name is highlighted on the folder list is renamed. Other folders whose check boxes are selected are not affected.
Selecting a Variable
• If no check box is selected on the variable list, any variable operation that is performed affects the variable whose name is currently highlighted on the list. If any variable check box is selected, only that variable is affected by a variable operation, and the variable whose name is highlighted on the list is not affected.
• When renaming a variable, only the variable whose name is highlighted on the variable list is renamed. If other variables are selected (checked), they will not be affected.
Folder and Variable Name Rules
The following are the rules that apply to folder and variable names.
• Folder or variable names can be up to 8 bytes long.
• The following characters are allowed in a folder or variable name: Upper-case and lower-case characters, subscript characters, numbers, underscore (_).
• Folder or variable names are case-sensitive. For example, each of the following is treated as a different folder/variable name: abc, Abc, aBc, ABC.
• A reserved word (system variable names, built-in function names, command names, etc.) cannot be used as a folder or variable name.
• A number, subscript characters or the underscore (_) cannot be used as the first character of a folder or variable name.
u To delete a folder
Important!
Before deleting a folder, make sure you no longer need any of the variables contained inside it. It is probably a good idea to first delete the variables you don’t need, move the variables you do need to another folder, and then delete the empty folder.
1. Open the folder you want to delete and check its contents.
• Make sure you no longer need any of the variables in the folder. If any of the variables are locked, unlock them.
• After checking the contents of the folder, close it to return to the folder list.
2. Select the check box next to the folder you want to delete.
• You can select and delete multiple folders, if you want.
3. On the folder list, tap [Edit] and then [Delete].
4. In response to the confirmation dialog box that appears, tap [OK] to delete the folder.
Tip: You cannot delete the “library” folder or the “main” folder.
u To input a folder name or variable name into an application
1. In the Main application, Graph & Table application, or some other application, move the cursor to the location where you want to input the variable name.
2. Start up Variable Manager to display the folder list.
3. If you want to input a variable name, double-tap the folder that includes the variable whose name you want to input. If you want to input a folder name, advance to the next step.
