Mountain Duck is a powerful utility tool that enables local management of cloud storage spaces. The software allows you to map cloud storage devices directly into your computer’s file explorer, or mount servers into the Windows file manager, enabling seamless access to your cloud storage from your local machine—just as easily as accessing your C: or D: drives. This greatly simplifies data uploads and downloads.
Mountain Duck helps users mount any remote FTP, SFTP, WebDAV, Azure cloud storage, S3, Google Cloud Storage, Google Drive, and OpenStack Swift as local disks within their system’s Finder, allowing cloud directories to be synchronized and managed locally. It also integrates cloud directories into Finder.app for synchronized management—operations such as uploading and deleting files remain in sync with the remote storage, making it highly practical and convenient.
