Windows 95, and applications written specifically for the Windows 95 environment, use a database called the Registry for storing configuration information. The Registry is roughly analogous to the .INI files used under Windows 3.x. Under Windows 95, Microsoft discourages using .INI files in favor of Registry entries. However, many applications (particularly 16-bit Windows-based applications) still use .INI files. Windows 95 supports .INI files (including WIN.INI and SYSTEM.INI) for compatibility with those applications.
.INI Master is a 16-bit application that can be run under Windows 95 to diagnose .INI files in the same way as under Windows 3.x.
