HOWTO: Locate Windows Special Folder Locations

• Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a, 6.0

SUMMARY

Windows 9x and Windows NT make use of many operating system special folders. These folders represent specific locations for application data, users settings, etc. It is possible to programmatically locate these folder locations using the SHGetSpecialFolderPath API function.

The following program displays the full special folder path to the Windows desktop. You can alter the program to show the full path of any of the special folders by passing the appropriate special folder constant to the SHGetSpecialFolderPath API call.

This program will only run on Windows 98 or Windows 95 and Windows NT systems that are configured with the Windows Desktop Update. The Windows Desktop Update can be installed from:
