The WOLF file extension is associated with a proprietary e-book format for the HanLin eBook reader. WOLF files store documents or e-books. This file type is obsolete and no longer supported.
WOLF files are found on Windows operating systems. Cool Reader is a common application for handling these files. The data in WOLF files is saved as Document Files.
If a game developer selects no encryption, WOLF archives may be packaged with the game executable. Since WOLF archives are encrypted, they are not meant to be opened by users, only referenced by the game.
You may need to update the application you use to open WOLF files. Only the latest versions support the current format. You should also scan WOLF files with antivirus software before opening.
Windows programs can automatically associate WOLF files with the appropriate software. If that does not work, you can manually associate the WOLF extension with software in the Windows registry.
Some all-in-one viewers claim they can display WOLF files, but they may show the data differently than software dedicated to the WOLF format.
