Titanium Media Sync is an Android app that allows you to easily sync a set of folders from your device to the cloud and back. It currently supports Dropbox, as well as your own FTP, SFTP, FTPS servers, without the need for the official Dropbox app.

This innovative app features a "setup & forget" sync engine that is battery-friendly and works on all Android devices. It will not slow down your device when no data changes and will backup your new/modified files, such as photos and videos, in the background as soon as possible. It also adapts to ever-changing connectivity and power conditions and offers powerful filtering features by file type, size, and more.

Titanium Media Sync supports two different sync modes: continuous sync from local to remote and one-shot sync from remote to local. It is compatible with all Android versions from 1.5 and up, making it accessible to a wide range of users.

However, it is important to note that Dropbox restricts uploads to 300MB per file. For more information, please visit the developer's website.

Overall, Titanium Media Sync is a reliable and convenient solution for syncing your folders with ease.
