Query the Registry for Folder Names

[This is preliminary documentation and subject to change.]

Requirement   (Designed for Microsoft® Windows® Logo)

Your application should not assume that folder names such as My Computer will be in English or will be unchanged by the user. Your application should query the registry directly to obtain the proper language-specific folder names.

Vendors should be aware that English versions of their applications might be installed onto non-English versions of Windows. In this case, a search for the English language directory string Program Files would not be successful and would result in a failed installation.

For many standard folders, a qualified path can be obtained by calling the SHGetSpecialFolderLocation function with the appropriate CSIDL constant. The following standard folders are accessible in this way.

Folders can also be located using the following Microsoft Windows NT® environment variables.

Standard Folder or Location Environment Variable
System drive %SystemDrive%
System root directory %SystemRoot%
Windows folder %windir%
Program Files folder %ProgramFiles%
User's profile folder %UserProfile%
User's temporary folder %Temp%

Access to specific user profile folders, such as Application Data, should be obtained through SHGetSpecialFolderLocation rather than by relying on the standard English folder name (as in %UserProfile%\Application Data\).
