When you use specialFolderPath("documents") on Windows, you get different
paths depending on which OS it is...

On XP, you get:

  C:/Documents and Settings/Ken/My Documents

On Vista, you get:

  C:/Users/Ken/Documents

Right - in both cases, you can use specialFolderPath(35) and it will resolve
properly on both platforms.

Tiemo is right though - on both Vista and XP, the Application Data (or
ProgramData) folder is a hidden folder that novice users won't have changed.

The general rule of thumb is:

  - Applications go into "C:/Program Files" (XP) or "C:/Programs" (Vista);
accessed with "specialFolderPath(38)"

  - Support files for the application that the user won't be getting access
to go in "C:/Documents and Settings/<user>/Application Data" (XP) or
"C:/Users/<user>/AppData/Roaming" (Vista); accessed with
"specialFolderPath(26)"

  - User-generated or user-accessible files go in "C:/Documents and
Settings/<user>/My Documents" (XP) or "C:/Users/<user>/Documents" (Vista);
accessed with "specialFolderPath("documents") or "specialFolderPath(5)"

  - Preferences/settings go in the Registry
