GRF Troubleshooting

Issues Opening GRF Files

Ragnarok Online Isn't There

If you attempt to load your GRF file, you experience a message such as "Can't Open GRF Files". If so, it typically means that you don't have Ragnarok Online installed for %%os%%. The OS won't know what to do with your GRF file, so double-clicking to load the file doesn't work.

Tip: If you know of another program that can open your GRF file, you can try opening it by selecting the application from the programs listed.

Incorrect Ragnarok Online Version

It is possible that your version of Ragnarok Online isn't able to open your Ragnarok Client Archive file due to incompatibility. You will need to download a newer version of Ragnarok Online if you don't have the right version. The primary cause of this problem is that your Ragnarok Client Archive file was created by a different (newer) version of Ragnarok Online than what's installed.

Tip: If you right-click on your GRF file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Conclusion: The majority of GRF file opening issues are due to not having the correct Ragnarok Online version installed.

More Causes of Problems Opening GRFs

Even with the correct version of Ragnarok Online installed, you can still experience difficulties opening GRFs. If you are still having problems opening GRF files, there may be other issues that are preventing you from opening these files. Problems unrelated to software:

• GRF file references in the Windows Registry are broken
• Accidental deletion of the description of the GRF file in the Windows registry
• Incomplete or bad installation of a software application associated with the GRF format
• GRF file corruption
• Past or present virus infection has affected your GRF
• Device drivers of the hardware associated with your GRF file are corrupt or out-of-date
• Your PC doesn’t have enough available resources to open the Ragnarok Client Archive file
