## Description

Since NAND applications store save data to system memory, a NAND application can read and write save data from another NAND application.

The `NA_LoadOtherTitleArchive` function will load save data of a specified NAND application as an `otherPub` or `otherPrv` archive. By using the FS library to access these archives, you can access save data of the specified NAND application.

The `NA_LoadOtherTitleArchive` function can only load a single save data region at a time. To access both public and private save data, or to access save data for multiple NAND applications, unload save data regions with the `NA_UnloadOtherTitleArchive` function each time you access a single save data region.

Only NAND applications can access save data from other NAND applications.

## Sample Demos

The NAND application sample demo `other_backup` reads and writes save data from another NAND application (the `backup` demo).

The `other_backup` demo is in the `$TwlSDK/build/demos.TWL/nandApp/other_backup` folder. The `backup` demo is in the `$TwlSDK/build/demos.TWL/nandApp/backup` folder.
