Turn on USB mass storage
To use the USB mass storage feature, you must have a media card in your BlackBerry device.
USB mass storage is designed to let you use your device as a USB drive. Using a USB cable, you can connect your device 
to a computer, car stereo, or other external device and access files on your media card.
Note: When USB mass storage mode is on, apps on your device can't access files on your media card.

Using a media card
Want more space to store your ring tones, videos, pictures, and songs? For additional space to save documents and media 
files, you can insert a microSD card into your BlackBerry device. Using a media card can help to increase the performance 
and power efficiency of your device.
You might be able to move large amounts of data by simply moving the media card into another device that supports the 
microSD card.
Supported media cards
Your BlackBerry device supports media card sizes up to 64 GB. Only microSD cards are supported.
To use a media card larger than 32 GB, you may need to format the media card to FAT32 format. You can use your device 
to format your media card.
Format your media card
You can format your media card to help resolve an issue with the media card. When you format your media card, all of your 
media card data is deleted.
