What is the .REF File Extension?

.REF File Extension Description:

The REF file extension is mostly used by various software as a reference file, which is a kind of document that works like conventional reference files, which are files that users refer to, when they want information or data about a specific software. The REF file extension is also used by various software as a cross reference file. As a cross reference file, this file extension refers or relates to synonymous or similar information in any location, within the same network.

The Ad-Aware application is an anti-spyware program that was developed by Lavasoft. The REF file extension's task for this application is to act as its signature file. The Ad-Aware application is used to detect and remove different spywares, and adwares that destruct the user's computer. Aside from its primary feature, the Ad-Aware is also capable of detecting dialers, malwares, Trojans, datamining, parasites, aggressive advertising, tracking components, and browser hijackers.

The REF file extension for the Ad-Aware is a short text file that was created to be used as a standard appendage for the application. With this, the computer system will always recognize the Ad-Aware. In fact, the REF file extension works much like an identification card or a signature, which will identify the uniqueness of the Ad-Aware application. Having the REF file extension with the Ad-Aware will aid in protecting the user's computer from dangerous, malicious, and pretentious files that may possibly use the Ad-Aware name to infiltrate the computer system.

Meanwhile, the REF file extension works as a temporary file for the Pro/Engineer. Pro/Engineer is computer-aided design software that is also capable of creating 3D graphics. It can be used with Microsoft Windows, UNIX, and Linux. Pro/Engineer also provides assembly modeling, drafting functionality, and solid modeling, especially for mechanical engineers. With the REF file extension, users are given temporary files that maybe downloaded from the Internet, which they can later use as a real permanent file.

The REF file extension can also be found as the document file of the ReferBib and an object reference file for the Train Simulator from Microsoft Corporation.
