About FolderSync
FolderSync is a cross-platform file synchronization app that connects your local storage to over 20 cloud services and remote servers. Available on Android, Windows, macOS, and Linux, it supports one-way and two-way sync with popular providers like Google Drive, Dropbox, OneDrive, Amazon S3, Box, and protocols including SFTP, FTP, FTPS, SMB, and WebDAV. What sets FolderSync apart is its deep automation and scheduling capabilities. You can schedule syncs at specific intervals, trigger them based on network availability or battery level, and integrate with Tasker on Android for fine-grained control. The built-in file manager lets you browse and manage files both locally and in connected cloud accounts, with support for file filtering by name, type, or date. Security features include AES256 encryption for data in transit and at rest, password protection, and two-factor authentication support. FolderSync offers a free version with ads and a one-time Pro purchase that unlocks an ad-free experience with all features. Developed by Tacit Dynamics, it has earned a 4.6-star rating on Google Play with over 22,000 reviews, making it one of the most trusted file sync tools for mobile-first workflows.
