When you run Windows version 3.1 File Manager or Windows for Workgroups (WFWG) version 3.1 File Manager under Windows NT, you receive the following error message:

16 bit Windows Subsystem
File Manager
An application has attempted to directly access the hard disk,
which cannot be supported.

If you choose Close, the 16-bit version of File Manager causes a general protection (GP) fault. If you choose Ignore, File Manager runs normally.


Windows 3.1 File Manager and Windows for Workgroups 3.1 File Manager attempt to directly access the hardware. This is not supported under Windows NT.


To work around this problem, choose Ignore instead of Close.

Additional query words: wfw wfwg prodnt winfile.exe "WOWEXEC caused an exception in the Win16 Subsystem" GPF gp-fault
