Our verdict on Filen
Filen is a cloud storage service built around client-side, end-to-end encryption for individuals and professionals. It supports uploading, organizing, synchronizing, sharing, and restoring files through web, desktop, and mobile applications. The feature set also includes network-drive mounting, file versioning, encrypted notes and chats, public file sharing, and command-line file management. Filen's apps are open source, and the service provides self-hosted WebDAV and S3 interfaces.
The published plans show a free account alongside four monthly Pro tiers priced in EUR. Pro I costs €1.99 per month for 200 GiB, while Pro II provides 500 GiB for €3.99, Pro III provides 2 TiB for €8.99, and Pro X provides 10 TiB for €39.99. Each paid tier includes unlimited bandwidth, unlimited uploads, client-side encryption, zero-knowledge technology, and syncing. The free account provides 10 GB, with deletion after three months of inactivity. This makes Filen a clear fit for users who want encrypted storage at a low entry price and can manage an account with that retention condition.
Platform coverage is broad: Filen lists web, Windows, macOS, Linux, iOS, Android, API, and self-hosted access. WebDAV and S3 interfaces extend its fit for network-drive workflows, storage tooling, and technical file management, while versioning and encrypted sharing support everyday collaboration around files. Users seeking encrypted synchronization, backups, restore points, and flexible access should find the feature mix well aligned with those needs. Users who prefer a simple consumer drive, avoid technical interfaces, or need a free account that remains available through long inactivity should consider another option.
