Sharing local files differs significantly from sharing cloud-based files. Local files reside on your physical devices like computers or USB drives, requiring manual transfer methods each time you share. Cloud files are stored on internet servers, enabling access through shareable links regardless of device location. The core difference is that sharing local files involves sending the file itself via transfer methods, while cloud sharing provides persistent access to a single file stored remotely.

Local file sharing relies on direct transfer mechanisms. Examples include sending files as email attachments or physically copying them onto a USB drive for someone else. Tools like Zoom screen sharing also allow showing locally stored documents during presentations. However, these always involve creating a duplicate or direct access during a specific session. Cloud platforms like Dropbox or Google Drive, conversely, let you generate a link granting access to the centrally stored file without needing the recipient to download it immediately (unless they open/save).

The primary limitation of local file sharing is accessibility. Both sender and recipient must coordinate the transfer method (like meeting for a USB drive), and files aren't accessible unless deliberately reshared. Cloud sharing offers greater convenience, real-time collaboration, and version control since everyone accesses the same file. Sharing local files via methods like email also raises security concerns if sent over unsecured channels, unlike permission-controlled cloud links that often include expiration settings or view/edit restrictions.
