HP File Manager for Slate 21 description
HP File Manager is a file management application that provides file browsing, copying, cutting, renaming, printing and other functions on local storage/USB drives/SD Cards. If there are multiple applications installed that can open a file, HP File Manager allows you choose which app to use. HP File Manager depends on device format support (e.g. if your device can read but not write NTFS volumes, HP File Manager will only allow you to read from the volume).
