Registration Database

The Registration Database is a source of information regarding applications and their OLE and association capabilities. This information is used in three cases:

by applications that support object linking and embedding
when you open or print a file from File Manager
for associating file name extensions with applications.

The registration database is set up and maintained by Windows and Windows applications. The database "REG.DAT" is located in the Windows directory (Under Windows 16-bit version). This file should not be moved or deleted. If the file is moved or deleted, loss of functionality in File Manager, Program Manager, and applications that support object linking and embedding, may occur. The Registration Database is modified by running the Registration Editor, REGEDIT.EXE.
