- TITLE :INF: _DEFAULT.BAT Does Not Exist in Windows NT
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system, version 3.1
- - Microsoft Windows NT Advanced Server, version 3.1
- ----------------------------------------------------------------------
-
- In Windows NT, when a user starts an MS-DOS application, the
- _DEFAULT.PIF file is called to create the virtual machine environment
- for the MS-DOS application. The program filename that _DEFAULT.PIF
- calls is _DEFAULT.BAT. _DEFAULT.BAT does not exist as a physical
- file. It is a dummy variable used as a placeholder to allow
- _DEFAULT.PIF to be saved. The MS-DOS executable file is substituted
- for _DEFAULT.BAT by the operating system.
-
- _DEFAULT.PIF should not be manually executed from anywhere inside
- Windows NT. The _DEFAULT.PIF file will be automatically used for
- MS-DOS applications that do not have a specific PIF file. If
- _DEFAULT.PIF is executed from File Manager, the following error
- message appears:
-
- "Invalid program file name, please check your PIF file."
-
- If changes are made to _DEFAULT.PIF, they will be used when MS-DOS
- applications without PIFs are started under Windows NT.
