What is an RFB file

RFB files mostly belong to TigerVNC.

Remote Frame Buffer (RFB) files are used in several specialized ways. The most common type supports remote desktop communication. In this case the file carries display data over a network using the RFB protocol, which is used by VNC software such as TigerVNC to show a computer screen remotely.

Another use of the RFB extension is for storing radiotherapy beam data. In treatment planning systems like RayStation, these files hold the calibration and parameter details needed for precise beam delivery in radiation therapy.

A third role designates the file as a RoboForm Bookmark File. Although less prevalent, this variation is used to manage bookmark information for the RoboForm application available at RoboForm.

Key details as outlined by FilExt.com:

Remote desktop data uses a streamlined protocol for transmitting pixel information.

Treatment planning files contain technical beam parameters important for medical calibration.

Bookmark files may be used by RoboForm to store web-related data.

FilExt.com note: For proper opening and viewing, use the application designed for the file's origin: a VNC client for desktop data, RayStation for beam details, or RoboForm for bookmark management.
