Mountain Duck is a paid Windows and macOS utility that mounts remote storage like FTP, SFTP, WebDAV, Amazon S3, Google Cloud, and more as local drives. Perfect if you want to open and save cloud files right from Finder or Explorer without syncing or bouncing between apps. There's a fully functional 14-day trial, too, so you can kick the tires before deciding to buy.

What is Mountain Duck?

Mountain Duck acts like a translator between your desktop and cloud storage. It maps your remote servers as local drives so you can use cloud files like they're sitting on your hard drive. There is no syncing, no browser windows, and no clunky upload or download routine. Just open, edit, save. Done.

Think of it like plugging in a USB stick, except instead of being physically connected, it could be something like an Amazon S3 bucket or a folder on an FTP server. Once mounted, you can open, save, rename, or move files using the same tools and apps you always use. No syncing, no browser logins, and no middlemen.

So when Mountain Duck mounts your Google Drive as D:, it's not copying files over, it's letting your system talk to Google Drive as if it's just another hard drive sitting inside your computer.

Why You Want This

If you work with remote servers, cloud storage, or any kind of off-site file system, this tool saves serious time. If you spend time editing code on a remote dev server, managing files in Backblaze, or pushing backups to S3, Mountain Duck makes it all native to your PC. Apps don't care if a file is in the cloud or not. They just see a local drive.

For example, Let's say you've got a pile of documents on Google Drive, and you want to work on them without the back-and-forth. You could download them, make edits, then upload them again every single time. Or you could just use Mountain Duck to mount Google Drive as a local drive, like D: Now you're editing files directly, just like they're on your computer. No more manual uploads or sync headaches.
