Opening DRF Files

The DRF file type is primarily associated with WinPEP.

DRF	File extension: DRF
	File type:	vehicle diagnostic information file

What is a DRF file?

DRF files mostly belong to WinPEP by Dynojet Research. DRF files are generated by a program called VIZ Render. This program is included with the older versions of a software used for the purpose of architectural design called AutoDesk AutoCAD Architecture.

Main use: Discreet Render Format enables its users to store rendered images of buildings, architectures, and other modeled structures. Discreet Render Format files can be opened in the 3DS Max program.
Limitations: The 3DS Max program does not allow its users to create DRF files. In order to create Discreet Render Format files, the users must use the VIZ Render program. Upon opening a DRF file using the 3DS Max program, the user must save the file in a MAX format. This is because the 3DS Max program does not support the creation of files in DRF format.

How to open DRF files

You need a suitable software like WinPEP to open a DRF file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your DRF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a DRF file directly in the browser:. Just drag the file onto this browser window and drop it.

DRF file format:

To find out what program is needed to open DRF files, you need to determine the file format. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). File extension, signature and file format must match; otherwise errors will occur when the file is opened. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Below you will find our evaluation of the DRF files:

The DRF file type is a very commonly used file extension and mainly uses a defined DRF format. The two most popular formats are as follows:

80% of all DRF files start with the bytes Document;, which are crucial for this file format. The contents of these files can even be read by a human. The file size is in the range of 22 bytes to 29 bytes. The file type is relatively new. The following keywords are characteristic: Document. These files are attributed to docx, docs, xlsx, acia, cfia, letter, agreement, management, request, admin and hall.
3% of all DRF files belong to Dynojet Run File. These files contain neither text nor words, but only data. Most of these files are 2 KB to 4 KB in size. The keywords Dynojet Research 2002, Dynojet Research Rev 1.0, WINPEP7, zero, 11:14:30 and Nov 18 1997 are typical for these files. Some examples of file names are RunFile_001.drf.

All the rest of the DRF files (17%) have different formats, the following 6 formats can be found: Virtuoso Display Resource File, XML and DRF. The category is rdims, application, district, tracks, cdnv, form or plan.

How to solve problems with DRF files

Associate the DRF file extension with the correct application.
Update your software that should actually open vehicle diagnostic information files. Because only the current version supports the latest DRF file format. Search, therefore, e.g. on the Dynojet Research manufacturer website after an available WinPEP update.
To make sure that your DRF file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
