.WAFF File

The waff file format is a proprietary file archive format used by Internet Explorer for the Mac, to store a collection of Webpages and linked documents.

Unfortunately, IE does not provide users with the ability to extract files from these archives.

This waff file type entry was marked as obsolete and no longer supported file format.
