QOL File Extension: What Is It & How To Open It?

Troubleshooting Problems Opening QOL Files

Common Problems Opening QOL Files

Binary Data is Not Installed

When you double-click your QOL file, you may see a dialog box from your operating system stating that it “Cannot Open This File Type”. If this is the case, it’s usually due to the fact that you do not have Binary Data for %%os%% installed on your computer. Because your operating system doesn’t know what to do with this file, you won’t be able to open it by double-clicking.

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

Wrong Version of Binary Data is Installed

In some cases, you might have a newer (or older) version of a Binary Data file that is unsupported by your installed application version. If you do not have the proper version Binary Data (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.

Tip: Sometimes you can get a clue about the version of QOL file you have by right clicking on the file, then clicking on “Properties” (Windows) or “Get Info” (Mac OSX).

Summary: In either case, the majority of problems opening QOL files are related to not having the correct software application installed on your computer.

Other Causes of QOL File Opening Problems

Although you might already have Binary Data or another QOL-associated software installed on your computer, you can still encounter problems opening Binary Data files.

These other problems include (listed in order from most to least common):

• Invalid QOL file references in the Windows Registry (the “phonebook” of the Windows Operating System)
• Accidental deletion of the description of the QOL file in the Windows registry
• Incomplete or bad installation of a software application associated with the QOL format
• Your QOL file is corrupted (issues with your Binary Data file itself)
• Your QOL is infected with malware
• Device drivers of the hardware associated with your QOL file are corrupt or out-of-date
• Your computer does not have the adequate system resources to open the Binary Data format
