NandFiler tool manipulates data in the system memory
(NAND). You can use it to delete, browse, and edit photo data, as well
as the save data of the NAND application stored in Wii system memory. By
using an SD Card, you can also use this tool to import and export save
Run it in the following ways.
NandFiler.srl to a DS Game Card and then running it
If you are running the TWL Nmenu using the IS-TWL-DEBUGGER software, a "Please wait a moment" dialog box appears, and you will no longer be able to perform operations in the IS-TWL-DEBUGGER software. To exit, click Force Quit in the dialog box.
There are three modes in NandFiler.
NandFiler tool starts in Filer mode by default.
In Filer mode, after you select either photo data, NAND application save data that has been already imported in the system, or SD Card data, you can browse and operate on that directory tree.
When you are browsing the contents of an SD Card, file and directory names will not appear if they use characters that cannot be converted to Shift_JIS.
The following table shows what operations you can perform.
|Displays a list of operations
|Switches pages for the displayed items.
|Selects files and so on.
|Confirms an item.
|Cancels the selected archive or file.
Moves to the parent directory.
|Opens a submenu when a file or archive is selected.
This is the state immediately after startup. The left side of the screen
displays links to the Game Code of the installed NAND application
(blue), and to photo data and the SD Card (purple).
Selecting a Game Code switches to archive selection in the center of the screen. Selecting a link to photo data or an SD Card switches to file selection on the right side of the screen. The following operations can be selected on the submenu displayed by pressing the X Button.
Copies files from the application's save data region or the PHOTO directory to the SD Card.
A directory is created on the SD Card (named either [
4-digit game code_4-digit version] or [
PHOTO]), and then the data is copied there.
Writes photo data to the PHOTO directory, leaving the photo region with zero available memory.
The photo data written using this process cannot be viewed with the Nintendo DSi Camera.
This process may take 30 seconds or more to complete.
Selecting a Game Code under Title Selection moves here. For Archive Selection, you can choose
These are links to the public save data, private save data, and
sub-banner of the NAND application selected under Title Selection.
The following operations can be selected on the submenu displayed by pressing the X Button.
However, the Backup and Break features do not exist in the sub-banner submenu.
Backs up save data on the SD card. The data backed up here can be imported using the
Restore operation, described below.
Backup differs from the
operation described above in that the entire file system of the save
data region is copied to the SD card, but with Export, data is copied in
Destroys the FAT system region of the save data. Use this for debugging an assumed problem with the save data region causing
FS_RESULT_BAD_FORMAT to occur.
This tool can restore the destroyed save data region through any of the methods described below.
To restore while the application is running, use
Initializes the save data and sub-banner. Restoration is possible if save data or sub-banner data becomes invalid using a break.
If PHOTO or SD have been selected under Title Selection, selecting any save data under Archive Selection moves to here.
A list of directories (yellow) and files (white) are displayed under File Selection.
When a directory is selected, press the A Button to browse the contents of that directory. When a file is selected, press the A Button to switch to View mode.
Following is the meaning of the information that is displayed at the top of the screen in File Selection.
|The time the file was created.
|The time the file was last modified.
|The time the file was last accessed.
REA: Read-only files
HID: Hidden files
SYS: System files
VOL: Volume level
PRO: Protected files
|Very bottom of screen
|Full path to the selected file.
This operation is valid for directories created with the
Export operation. Note, however, that exported PHOTO directories cannot be imported.
This operation copies data to the save data region of system memory. Provided the data does not exceed the size of the save data region of system memory, the data copied over by
Export can be imported even if they have been altered.
Deletes a file or directory. If a directory is selected, files and directories inside the directory are deleted recursively.
This operation is only valid for save data backup files created using
the Backup feature. The backup file on the SD card is imported to system
Note that importing backup files will fail in the cases given below.
In View mode, you can view file contents. The displayed filename and addresses are shown on the upper screen.
The following specifications apply to the display of characters.
0x00 can be replaced by
0x20 (by a space)
0x7A conform to ASCII code
|Scrolls one page at a time.

Pressing the L or R Buttons in the editing state will change the value at the current cursor position.
