About this app

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.

I haven't really used this app that much, but it seems like it mostly does a good job. However, one thing that irks me is that uploaded files/folders don't have the same timestamp as the local files/folders (and vice versa, I guess). Would it be possible to also sync timestamps when syncing files (and folders, but especially files), or does OneDrive's API not offer that functionality?

Sadly, the app can no longer be used to sync save files for games that store save files in the Android/data folder. This has made the app obsolete for me. When it did work, it was absolutely great however, so if you do not need the app for this situation, it is a great app. I hope the developers can find a solution to this (since many users have paid for the pro version), albeit this is more Google's fault.

Hi, if you use our app to sync files in private folders inside Android/data, then indeed it's not possible anymore. This is a restriction imposed by Google in recent Android versions. As you said it is not the fault of our app. Sync continues to work perfectly fine for all other files in the device storage.

PLEASE ADD THIS FEATURE! Can you please add a feature where if it doesn't sync one file it'll atleast push on to the next one. Special characters like æß vç AND ESPECIALLY JAPANESE CHARACTERS and a million others won't sync and will cancel the whole thing. And then when it's done just show the ones that couldn't sync PLEASE!!!!!
