This app is an automatic file sync and backup tool. It lets you automatically synchronize files and folders with Microsoft OneDrive cloud storage and with your other devices. It is an ideal tool for photo sync, document and file backup, automatic file transfer, automatic file sharing between devices,...

New files in your cloud account are automatically downloaded onto your device. New files in your device are uploaded. If you delete a file on one side, it will be deleted on the other side. It works across multiple devices (your phone and your tablet). If their folders are synced with the same cloud account, they will be kept in sync with each other.

This is how OneDrive works on computers but not on Android. Two-way automatic synchronization should be an essential function of the official app. For whatever reason, it is not the case. OneSync is here to fill the gap.

All file transfers and communications between user devices and cloud storage servers are securely encrypted and do not go through our servers. No outsiders will be able to decrypt, see or modify any file contents.
