WTF (Windows Text File) is a plain-text file format developed by Microsoft. It is intended for storing text information in readable form. Many users report problems opening it, because most systems don't know what to do with the .wtf file extension. The resulting error messsage "WTF? Unknown file extension!" is widely known. The chat acronym WTF is commonly used to signify uncertainty or unpleasant surprise.
As part of Microsoft's effort to develop free, open, user-friendly software environments, it is constantly improving file formats. After WMV (Windows Media Video) and (WMA - Windows Media Audio), it published proposals for WMP (Windows Media Picture) and WTF (Windows Text File) in May, 2006.
"WTF?" is the usual response by many users, who are not sure how Microsoft intends to compete with TXT format. Microsoft's release timeline calls for the TXT format to be made obsolete within months, by disallowing Windows Vista to open .txt files.
