Features

Everything You Need

Built for power users. Simple enough for anyone.

🌐

Browse Files from Anywhere

A secure Cloudflare tunnel spins up automatically when you mount a drive. Share your files from any browser, anywhere — no VPN, no port forwarding. Fresh credentials every session.

🔐

End-to-End Encryption

AES-256 client-side encryption via rclone crypt. Files are encrypted on your machine before they ever reach the cloud — not even the provider can read them.

🖥

Native Drive Letters

Files appear in Explorer, File Save dialogs, and every app — just like a USB drive. Your cloud shows up with your chosen name.

🔒

Private by Design

OAuth tokens and keys stay on your machine in %AppData%. Nothing is collected, phoned home, or transmitted to us — ever.

Lightweight & Fast

Runs efficiently in the background — single process, under 100 MB RAM. Smart single-instance design keeps your system clean.

🔄

Auto-Mount on Startup

Drives mount automatically when Windows starts — your files are ready before you open the app. Per-drive toggle in settings.

📊

Bandwidth Throttling

Throttle upload and download speed per-drive live from the UI — so cloud sync never hogs your connection.

🗂

Up to 5 Drives

Manage up to five cloud drives simultaneously from one clean interface — mix providers freely.

📁

Smart File Browser

The built-in remote file browser shows file type icons, formatted sizes, individual download buttons, and ZIP download for entire folders.

🆓

Completely Free

No paywalls, no subscriptions, no telemetry — now or ever. Free to download and use, forever.

Frequently Asked Questions

Does it work without admin rights?

The first install requires elevation to set up WinFSP. After that, A to Z Drive runs without admin rights.

Is my data sent anywhere?

No. All credentials are stored locally in %AppData%\A to Z Drive. Nothing is collected or transmitted to us.

What is WinFSP?

WinFSP is an open-source Windows file system driver that enables virtual drive letters. The installer handles it automatically.

How many drives can I add?

Up to 5 simultaneous drives in the current version.

Which Windows versions are supported?

Windows 10 and Windows 11, 64-bit only.

How does Browse Files work?

When you mount a drive, A to Z Drive automatically creates a secure Cloudflare tunnel. You get a unique HTTPS URL and per-session login credentials — share them with anyone or use them yourself on any device. The tunnel and credentials are destroyed when the drive unmounts.

How does encryption work?

Encryption uses rclone's built-in crypt backend with AES-256-CTR. Files are encrypted locally before upload — only you hold the key. Enable it per-drive in the app's drive settings.
