HP File Manager is only for HP platforms shipped with Android 4.4 and above. It will not work with other devices. 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).
