Only ExpanDrive

What none of these other tools can offer.

The drive letter is the part you see. The platform behind it, and the server-side companion, are the parts that decide whether the tool holds up at work.

Common questions

ExpanDrive vs Mountain Duck.

The questions buyers actually ask when they're choosing between us. Answered straight.

No. Mountain Duck integrates Cryptomator so your cloud provider only ever sees ciphertext. ExpanDrive ships TLS in transit, OAuth and SSH-key auth, and end-to-end encryption is on the Files.com platform — not in the desktop tool. If zero-knowledge cloud encryption is the deal-breaker, Mountain Duck is the right pick.
