Identification

• A file with the .waf file extension is known as an Internet Explorer cache file.
  
  

Systems

• Waf files are only found on the Mac OS version of the Internet Explorer program.
  
  

Function

• A .waf file contains the cache or record of files that you have accessed with Internet Explorer. The .waf file extension serves as a marker, allowing Internet Explorer to locate the file when it is needed.
  
  

Use

• Like other web browser cache files, .waf files allow your computer to remember some information about the website so that it takes less time for the site to load.
  
  

Considerations

• The .waf file is not meant to be manually accessed. If you attempt to double-click on a .waf file, you are likely to get an error message.
