Your phone has the following storage types for your apps, data, and files.
- Phone storage. This storage combines both the internal storage, where apps, email, data, and text messages are stored, and the file storage, where photos, videos, and music files are kept. When you are running out of phone storage, you can free up space by uninstalling apps, changing download settings, or moving files to your computer or to an online storage service.
- SD card (SD card). Use your SD card (purchased separately) as a removable storage to store and access your media and other files on HTC 10 or any Android phone, or set it up as an extension of the internal storage. See SD Card Storage Settings.
- USB storage. When you plug in an external USB storage device (such as a USB flash drive or an SD card reader), you can view photos and videos stored on the device right from Gallery and play songs stored on the device in Music. You can also open PDFs and edit Office documents.
You need a special cable adapter to connect your phone and a USB storage device. Your phone supports USB storage devices (except portable hard drives) up to 64 GB.
- Online storage. If you’re using an online storage account that’s accessible from your phone, you can store your files to your online storage.
