FolderSync vs ownCloud

FolderSync moves files between folders on a device and cloud services or file servers, and it can also sync folders stored on the same device. One-way sync mirrors a source to a destination; two-way sync is also supported. It can transfer files between two remote locations through an Android device or desktop computer, which temporarily holds the files. Connections include Google Drive, Dropbox, OneDrive, Box and Nextcloud, along with FTP, SFTP, SMB, S3-compatible storage and WebDAV. Its V2 engine adds encryption, pre-sync change analysis, parallel transfers and Cron-based scheduling. FolderSync also supports Tasker integration and configurable events such as schedules and syncs. Encryption protects file names and contents before upload, but works only with one-way sync; a lost encryption password cannot be recovered. FolderSync says account, folder-pair and sync-log data stays on the device, while files go directly to the configured service or server. A free plan is available. Android requires version 8.0 or newer; desktop support covers Windows 10 or newer, macOS 10.15 or newer, and qualifying 64-bit x86 Linux systems.

ownCloud is open-source file sync, sharing, and content-collaboration software for teams working across devices and locations. Teams can share internally or externally, invite guests, create file drop folders, comment, and collaborate in real time. It supports Windows, macOS, Linux, iOS, Android, and web access, with file versioning, zero-knowledge encryption, and business administration controls. Deployment options include on-premises, a cloud of choice, or ownCloud.online, hosted on servers in Germany. External storage can bring services such as S3, Dropbox, and SharePoint into a single access point. Microsoft integrations include Office Online Server, Office 365, and Microsoft Teams; Collabora Online supports collaborative browser-based editing of documents, spreadsheets, presentations, and diagrams, with live changes and revision history. The ownCloud.online plans list 256-bit AES and SSL/TLS encryption, multi-factor authentication, end-to-end encryption, and a File Firewall. The Community plan supports unlimited users; Standard and Enterprise start at 25 users. Hosted options cover one to four users with 500GB, or start at five users with 1,000GB and 200GB extra storage per additional user.
