Direct answer
An invited guest can join an active HTTPS session through a supported browser without installing Glass Desktop Box. Depending on the host's permissions, the guest can view shared items, download files, upload files or folders, replace permitted content and chat with the host. A direct P2P route is attempted when possible, with relay transport available when required.
Who this guide is for: Light: €11.99 net · Starter: €22.99 net · ProBox: €59.99 net · ProBox XXL: €99.00 net · ProBox Duo: €99.00 net · ProBox Duo XXL: €169.00 net. Light includes 1 GB, Starter 5 GB and ProBox 25 GB of relay file transfer per month. ProBox Duo includes two independent licences with 25 GB each, not a shared pool. Direct P2P transfers do not consume this allowance; availability depends on connection conditions. Light and Starter share files through a browser; ProBox and ProBox Duo additionally support shared Boxes on each participant’s desktop. All participants need a ProBox licence for that feature. All four plans permit private and commercial use. The one-time purchase includes twelve months of online services starting with each licence’s first successful activation, not purchase. Each ProBox Duo licence starts independently. The first activation is recorded; reactivation does not restart the term. There is no automatic renewal or further charge, and no cancellation is needed to prevent renewal. Continued online use requires a voluntary new purchase with its price and service period shown beforehand.
Invitation and guest access
The host creates an invitation link and PIN. The guest opens the HTTPS page, enters the requested identity information and joins the active session. No separate Glass Desktop Box account is required for the supported guest workflow.
The invitation page, active session and end page are parts of one product experience, but design changes must never remove upload, download, replacement or chat behavior.
Transfers and limits
Browser-based Remote transfer currently supports individual files up to 1 GB. Monthly allowances depend on the host's plan. A direct device-to-device route is attempted first; a compatible relay may carry the data when network conditions prevent direct transfer.
- Files and folders can be selected or dropped into the upload area
- Each failed item needs an understandable reason
- The host controls the active session and permissions
- Relay transport is not permanent cloud-file storage
When an upload or download fails
Common causes include an ended session, insufficient transfer reservation, a size or plan limit, a locked file, interrupted connectivity or an unavailable host. The interface should retain the affected item in upload history and explain the failure without exposing raw implementation errors as the only guidance.
For help, record the time, filename, size, browser and displayed message, then contact support@glassdesktopbox.com.
Important limitations
- The host and guest must remain connected for an active direct session.
- Network conditions can require relay fallback or interrupt a transfer.
- Received content must be treated as untrusted until scanned by appropriate security software.

What does peer-to-peer file transfer mean?
Peer-to-peer transfer is designed to send data directly between participating devices whenever technically possible instead of first storing the file in a permanent cloud folder.
What happens when a direct P2P route is not available?
A compatible relay route may be used to complete the transfer. A relay is a transport fallback, not a permanent user file archive.
What is the maximum file size for a Remote file transfer?
For standard Remote file transfers, the maximum upload size is 1 GB per file.
Does the recipient need to install the application?
A recipient can use the HTTPS guest page for supported browser-based transfers without installing the application. Shared ProBox workspaces require compatible Glass Desktop Box software and the appropriate access.
What can an HTTPS guest do?
During an active invitation, a guest can view shared files, download permitted items, upload files or folders to the host, replace permitted files and use the session chat. The exact controls depend on the host's session and permissions.
Are transferred files permanently stored in cloud storage?
The product is designed for direct or relayed transfer rather than permanent cloud-file storage. Connection services may establish or relay a session, but they are not presented as a permanent user file archive.
Why can an upload fail?
An upload can fail if the session ended, storage reservation is insufficient, the file is locked, a size or plan limit is exceeded, the connection is interrupted or the host is no longer available. The interface should identify the affected item and provide a useful reason instead of only showing a technical code.
