Microsoft® Windows 95® not only supports the complete set of Microsoft® MS-DOS® system functions and interrupts but also provides extensions that permit MS-DOS – based applications to take advantage of Windows 95 features, such as long filenames, exclusive volume locking, virtual machine services, message services, and program information file management. For more information about these topics, see the articles with those names in this guide. For more information about MS-DOS functions and interrupts, see the Microsoft MS-DOS Programmer's Reference.
