What it does

Your computers, finally connected

Link your Windows and Mac machines to Erupt DM and files flow between them — automatically, instantly, invisibly.

AirDrop Alternative for Windows

AirDrop only works between Apple devices. Erupt DM pairs any Windows 10/11 PC with any Mac — transfer wirelessly, no cable, no cloud drive.

Send Large Files Without Limits

No size caps, no throttling, no “file too large” errors. Move the 4K project, the disk image, the raw footage.

Sync Folders Between Two Computers

Drop a file into the sync folder at home — it's already on your office computer when you arrive. Silent auto-sync in the background.

End-to-End Encrypted by Design

Data is encrypted on your device and decrypted only on your other devices. Nobody in between can ever read it.

Interrupted? It Resumes

Cut the connection mid-transfer? Erupt DM continues from the breakpoint, and offline machines catch up the moment they're back.

One Library on Every Desk

Downloads, queues and history stay identical on every paired machine — start a task on one, find it finished on the other.

Drop files into the sync folder or send them straight from the download list — they arrive before you do.

FAQ

Frequently asked questions

Is there an AirDrop alternative for Windows?

Yes. AirDrop only works between Apple devices, so Windows PCs are left out. Erupt DM pairs Windows and Mac computers directly — transfer files wirelessly, no cable and no cloud drive in the middle.

How do I transfer files from Windows to Mac?

Install Erupt DM on both machines, pair them once with a pairing code, then drop files into the sync folder or send them straight from the download list. Files appear on the other computer automatically.

What is the maximum file size?

There isn't one. Sync any file of any size — video projects, disk images, raw footage — with no caps and no throttling.

Is the transfer secure?

Yes. Transfers are end-to-end encrypted: data is encrypted on your device and only decrypted on your other devices. Devices authorize each other with a pairing code, so data flows only between your own machines.

Do both computers need to be online at the same time?

No. If one device is offline or powered down, it catches up automatically the moment it's back — nothing is lost.

Can I sync folders automatically between two computers?

Yes. Anything you drop into the sync folder distributes to your paired devices in the background — no manual uploads.

Which platforms are supported?

Windows 10/11 (64-bit) and macOS 12+ (Apple Silicon and Intel). Both platforms get the same feature set.

Is Erupt DM free?

You can download and try every feature free for 14 days — no signup. See the official website for licensing options.
