Select the local directory where you want the synced files to live.
Traditional cloud storage (Dropbox, Google Drive, OneDrive) relies on accounts and permission lists . To share a folder, you must invite specific email addresses. This creates a dependency on a central server (authentication), limits sharing to registered users, and creates friction when sharing large files with external teams. resilio sync key
