You could use the environment variable AllUsersProfile[0] for this.

Another way to do this:

Prelude> :m System.Win32 Prelude System.Win32> sHGetFolderPath nullPtr 35 nullPtr 0 "C:\\Documents and Settings\\All Users\\Application Data"

Thanks, this is what getAppUserDataDirectory (from System.Directory) is doing: getAppUserDataDirectory :: String -> IO FilePath getAppUserDataDirectory appName = do ... s <- Win32.sHGetFolderPath nullPtr Win32.cSIDL_APPDATA nullPtr 0 ... I think your path above is the correct location on Win32; in that case, Windows makes it available[1] as CSIDL_COMMON_APPDATA. System.Win32 doesn't use this constant at the moment, but I think it could go in [2] along with the rest of them. Then, System.Directory could provide getAppGlobalDataDirectory as you suggest. A patch looks easy, but I'm not sure that I would call /etc the "global data directory" on Unix. I'll have to think about it some more.
