What is a DUB file?

A DUB file is a Windows system file used to add a spelling dictionary to Windows applications, such as Microsoft Word and Internet Explorer. DUB files, the most notable of which is MsSp7en-us.dub, are found in the C:/Windows/Globalization/ELS/SpellDictionaries directory.

More Information

Windows spelling dictionaries are comprised of three files: a .LEX file, an .ACL file, and a .DUB file. The LEX file contains data used to check a user's spelling and grammar, the ACL file contains data used to auto-correct a user's spelling and grammar mistakes, and the DUB file contains a small amount of data that, potentially, is used to identify the dictionary's language. However, at this time, LEX files' true purpose is unknown.
