What is foldedcloud?

Folded Cloud is a desktop application that turns your Telegram account into personal cloud storage, mounted as a real network drive on your operating system. Instead of paying for a cloud storage service, it uses Telegram's infrastructure to store your files, with no storage caps and no monthly fees. The application works by connecting to your Telegram account and exposing your stored files through WebDAV, a protocol that lets operating systems treat remote storage like a local disk. On macOS, this means you can open Finder and browse, upload, or stream files from Telegram just as you would from a normal folder. Large files are automatically split into optimized chunks to stay within Telegram's individual file size limits, then reassembled transparently when you access them. Privacy is handled locally: all session credentials, encryption keys, and file metadata are stored on your own machine. There are no intermediate servers between you and Telegram. The application is currently optimized for macOS and is available as a downloadable installer. Setup involves installing the app, signing in to your Telegram account via QR code or phone number, and then connecting Finder to the local address the app provides. The roadmap includes Windows and Linux support, end-to-end encryption for stored files, and a search feature with document indexing. The technology stack includes a Rust backend for performance, a Tauri v2 and React desktop interface, a native MTProto implementation for Telegram communication, a custom WebDAV layer, and a local SQLite database for indexing. The app's core source code is kept in a private repository.
