Cross-Cloud Folder Sharing by cloudHQ lets you share a folder across different cloud services so everyone works in their own platform while files stay 100% in sync. It supports Google Drive/Shared Drives, Dropbox, Box, Microsoft SharePoint, OneDrive, Egnyte, and Amazon S3, creating a two-way continuous sync after you invite users via email.

Manage your cross-cloud folder shares from the cloudHQ sharing dashboard: view members and roles, invite or reinvite people, remove users, unshare a folder, or leave/decline a share. Stopping or leaving a share halts sync immediately but does not delete files already in anyone’s cloud account.
