Summary

FolderSync syncs folders between devices and cloud providers or file servers, and can also synchronize two folders on one device. It supports one-way mirroring and two-way sync, as well as transfers between two remote locations using an Android device or desktop computer as a temporary intermediary. Supported services include Google Drive, Dropbox, OneDrive, Box, and Nextcloud; protocols include FTP, SFTP, SMB, S3-compatible storage, and WebDAV. Its V2 engine adds cloud-to-cloud sync, encryption, pre-sync change analysis, parallel transfers, and Cron-based scheduling. FolderSync also documents Tasker integration and configurable automation events. Encryption protects filenames and contents before upload, but works only with one-way sync, and a forgotten encryption password cannot be recovered. FolderSync says account, folder-pair, and sync-log data remain locally stored, while files go directly to the configured provider or server. The free plan is available on Android and desktop; the Android app requires version 8.0 or newer, while desktop support includes Windows 10 or newer, macOS 10.15 or newer, and qualifying Linux systems.

Who it is for

FolderSync suits people who need folder synchronization across devices, cloud services, or file servers. It may also fit users who want scheduled or event-based automation, provided they account for its platform requirements and encryption limits.
