Opening a GRF File

The GRF file type is primarily associated with Ragnarok Online.

GRF	File extension: GRF
	File type:	game archive file

What is a GRF file?

GRF files mostly belong to Ragnarok Online by Gravity. The GRF file extension is used by generic graph files associated with multiple applications like Graph Edit, Golden Software Grapher, DPlot and MicroGrafx Graph Plus etc. These 2D and 3D graph plotter programs use GRF file format to store their project files created by the user.

Main Usage: The GRF file format is used to store data in graphical format. It saves the graph type and related data points defining key points and variables. These are widely used for 3D projections, polar charts, triangle plots, probability charts, hydraulic scales and others. Not only do they support different graph format, but also advanced plotting types such as box-whisker and hi-low close plots etc.
Associations:
- Ragnarok Client Archive: Game files related to a multiplayer game called Ragnarok Online use GRF file extension. This file format was developed by Gravity. The compressed file archive is used by the Ragnarok Online for saving compressed images, sounds and other data files.
- CloverDX Data Transformation Graph: Javlin CloverDX Designer uses GRF file extension for its data transformation files. These files are saved in XML format and store a diagram of data writers, manipulators, transformers and data readers.

How to open GRF files

You need a suitable software like Ragnarok Online to open a GRF 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 GRF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a GRF file directly in the browser:. Just drag the file onto this browser window and drop it.

GRF file extension format:

A file format defines how the data in the file is structured. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. If there are problems opening a file, you must first determine the file format used. In the following you will find our evaluation of the GRF files:

GRF is a very common file type and is used by a few programs, each with its own file format. The two most popular formats are as follows:

25% of all GRF files start with the bytes Master of Magic, which are crucial for this file format. These are binary files, so they do not contain words or text. The files are 5 MB to 2 GB in size, with a median of 750 MB. This file type is based on cutting-edge technology. The files contain the following words: Master of Magic. The following filename is common: Data.grf. Files like these are about gepard, rdata, sdata, tdata, prontera, darkro, adata, patch, aste and card.
20% of all GRF files internally use the Microsoft Compound File format, also known as Composite Document File format or OLE2 compound document format. This is a complex container format used by earlier versions of Microsoft Office and other Windows programs. The file signature of compound files is defined as D0 CF 11 E0 A1 B1 1A E1, so the first character of a file looks like "DOCFILE". There is also a globally unique identifier 8d6e4ac5-7840-11d0-8fe4-444553540000 or b0d9b8e0-d030-11cf-8dfa-00aa001a2d56. Sections and streams in the file have names like VBAProject and CONTROLSAVESTREAM. The files are 7 KB to 1 MB in size, with a median of 150 KB. Such files sometimes refer to graph, profile, plot, parameters, title and section.

The remaining 55% of all GRF files are files with no common format, the following 19 formats can be found: OpenTTD Graphics Resource, GS Draw drawing, XML, config, RIFF, ZIP, UTF-8, GRF, DPLOT, ntr and Graph. They are often associated with logo, base, label, ogfx, curve, serie, trial, cztr or load. Just click the "Choose your .grf file to analyze" button on this page to find out what your GRF file is.

How to solve problems with GRF files

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