Your NOOK supports microSD cards up to 256GB (not included).
To install a microSD card, carefully insert the card as shown below into the card slot until it clicks and locks into place.
To remove the microSD card, gently press it inward to eject.
The SD card functions in two ways:
1. Portable Storage (Default and recommended)
This option is recommended for users who only plan to use their SD card for media storage, or plan to switch between multiple SD cards. The default write disk will be set to Internal Storage, which means that all captured photos & video, screenshots, downloaded Ebooks, etc. are stored in Internal Storage.
If you want to change the default write disk to SD card, you can do so by going into Settings > Storage & USB, then select the SD card as Default write disk.
Some eBooks can only be downloaded to SD card from your Library once you enable the settings from NOOK Settings.
2. Internal Storage
This option is recommended for users who wish to expand the existing storage of their tablet, and plan to always keep their SD card inserted. This option adopts your SD card into the tablet’s internal storage to increase storage space for supported apps and data.
Removing the SD card after it is set to Internal storage will prevent access to all apps and data stored on it until it is re-inserted. Your SD card will also not be readable by other devices until it is formatted.
How to change/format from Portable Storage (Default) to Internal Storage:
1. Insert SD card.
2. Tap on the notification prompt.
3. Select “Use as internal storage”.
4. Complete the prompts until internal storage format set up is finished.
Configuring the NOOK App for the microSD Card
1. After inserting and configuring your microSD Card, open App Drawer > Nook Settings.
2. Select “Download & Storage” and check “Download to SD card”. Eligible NOOK Content will be stored on the microSD.
Digital Rights Management and Publishers guidelines will affect the list of content eligible for downloading on an SD card.
