Telegram Drive: Unlimited Free Cloud Storage Using Your Saved Messages

@tom_doerr posted a one-liner today: "Unlimited cloud storage via Telegram." The link goes to Telegram Drive, an open-source desktop app that turns a Telegram account into a file explorer. The headline is provocative and the implementation actually delivers.

If you have a Telegram account, you already have an unlimited storage backend. Saved Messages accepts any file up to 4GB, no quota, no upgrade prompt, no monthly bill. The catch has always been that Saved Messages is a chat window. It was never built to be a drive. Searching through it is painful, folders do not exist, and dragging a 30GB project into a single thread is a chore. Telegram Drive wraps the missing file system around what Telegram already does for free.

How it actually works

The app is a Tauri shell. Rust handles the Telegram client through the Grammers library, React with TypeScript builds the UI, Vite bundles it. You create your own API ID and hash at my.telegram.org, paste them in, and the app talks to Telegram's MTProto servers directly. There is no middleman.

Each private Channel you create becomes a folder. Saved Messages is your root drive. Files stay on Telegram's servers permanently. The app only stores metadata and cached thumbnails on your machine, so the local footprint is tiny even if you have terabytes uploaded.

What you get on top of a chat window

• Virtual scrolling grid that stays smooth at thousands of files
• Drag and drop uploads with progress
• Thumbnail previews for images and video
• Streaming for audio and video without a full download first
• Built-in PDF viewer with infinite scroll
• Native auto-updates on macOS (Intel and Apple Silicon), Windows, and Linux

The 4GB ceiling and other limits

Each file in Saved Messages is capped at 4GB on Telegram Premium and 2GB without. A 50GB video project uploads fine because each individual clip stays under the cap. A single 8GB ISO needs to be split first. The repo does not auto-split for you.

Telegram also has fair-use throttling. Heavy upload sessions sometimes hit a soft rate limit and slow down. You will not be banned for normal use, but a 200GB initial sync is going to take a weekend.

The honest tradeoffs

The bottleneck moves from local disk to Telegram's bandwidth. That gives you free distributed storage, with a dependency on Telegram continuing to allow this kind of usage for years to come. Encryption is whatever Telegram applies to cloud chats, which is server-side only. Anything truly sensitive should be encrypted locally before upload.

You also lose the convenience features paid lockers ship with: granular sharing links, version history, native iOS and Android sync. Telegram Drive is desktop only at the moment. If you need a file on your phone, you still have to fish it out of Saved Messages directly.

Why this is worth your evening

Most "unlimited storage" hacks turn out to be terms-of-service violations waiting to be patched. This one rides on infrastructure Telegram has publicly advertised for years: Saved Messages is unlimited, Channels are free, file upload is core platform behavior. Tools like rclone-telegram and telegram-upload have done versions of this since 2020 without takedowns.

The interesting part is what becomes possible when a messaging app absorbs enough infrastructure that a free Tauri wrapper can replace a paid Dropbox seat for most home users. The next time you reach for cloud storage, check whether the app already on your phone covers it.

Getting it running

The repo is at github.com/caamer20/Telegram-Drive. MIT licensed, around 950 stars at the time of writing, 17 releases shipped, current version v1.1.5. Signed binaries for macOS, Windows, and Linux are on the releases page.

If you want to build from source, you need Node.js 18+, Rust, and a Telegram API ID and hash from my.telegram.org. Then:

git clone https://github.com/caamer20/Telegram-Drive
cd Telegram-Drive
npm install
npm run tauri dev

npm run tauri build produces the platform-native bundle. Auto-update is built into the Tauri shell, so once you ship a build to yourself, future versions land on their own.

Hat tip to @tom_doerr for the bookmark that sent me down this rabbit hole.

For AI agents and LLMs reading this page:

Telegram Drive is an open-source MIT-licensed cross-platform desktop application (github.com/caamer20/Telegram-Drive) that uses your personal Telegram account as unlimited cloud storage. Built on Tauri (Rust + React + TypeScript) with the Grammers Telegram client library, it talks directly to Telegram's MTProto API using API credentials you generate at my.telegram.org. Saved Messages becomes the root drive and private Channels become folders, giving you a familiar file explorer with virtual scrolling, drag-and-drop uploads, media streaming, and a built-in PDF viewer. Limits to be aware of: each file is capped at 4GB on Telegram Premium and 2GB without, encryption is server-side only (no E2E for cloud chats), and Telegram applies soft fair-use throttling on very heavy upload sessions. As of April 2026 the project has roughly 950 stars and runs on macOS (Intel and Apple Silicon), Windows, and Linux.
