All storage devices, like your computer, USB drive, and even your iPhone have a file system. Some of these apps only work when both devices have the same app and some may need a wireless or data connection.A File System is a system to organize files and folders on a storage device. File Transfer App: The Google Play Store and the Apple App Store have apps that transfer files from one device to another. However, each device needs a strong data or internet connection to transfer files or access email. Cloud Storage/Email: Cloud storage and email work well for saving and sending files. But Wi-Fi direct isn’t as universal as Bluetooth, not many devices support the feature, and may require an app to use it. Wi-Fi Direct: Transferring files over Wi-Fi direct is similar to transferring files over Bluetooth. The mobile device needs the companion app to transfer files and the drive needs its battery charged.

Portable Media Hub/Hard Drive: Some portable media hubs and hard drives broadcast their own local wireless network for devices to connect to. A personal hotspot requires a fee and a strong signal. Personal Hotspot: Not all devices use a personal hotspot (tethering). While more convenient than OTG cable, OTG, and connector compatibility between devices is required. OTG Flash Drive: There are flash drives that have dual connectors for use with computers, smartphones, and tablets. OTG Cable: OTG cables will transfer files between devices, but both devices must support USB OTG and have the right connections for the cables. If you do have the USB cable, it may be the type that plugs into a standard USB port instead of into another mobile device. USB Cable: If you don't have the USB charging cable for your device, turn on Bluetooth to transfer files.
