The Index.dat file
index.dat is a file used by the Internet Explorer web browser. The index.dat file functions as an active database, which runs as long as a user is logged on in Windows. It functions as a repository of redundant information, such as web URLs, search queries and recently opened files. Its role is similar to that of an index file in the field of databases, where a technique called "indexing" stores the contents of a database in a different order to help speed up query responses.
