But the path can still vary from OS to OS. Are you retrieving this path using the API (for example, SHGetSpecialFolderPath)? If your app still needs to support Win95 and WinNT4, you probably need to write extra code to ensure compatiblity or settle on a different folder, such as "My Documents" (still need to use SHGetSpecialFolderPath to get that as it will be different from OS to OS, and even determine if you want it for all users or only the logged in user). -- Mike

What i already did in one of my programs is what the link that Karl pointed explained, that is: check first if it is NT, then the Shell version: Public Function FolderToWrite () As String If IsNT Then If ShellVersion >= 5 Then FolderToWrite = GetAppDataFolder End If End If If FolderToWrite = "" Then FolderToWrite = App.Path End If If Right (FolderToWrite, 1) <> "\" Then FolderToWrite = FolderToWrite & "\" End If End Function I wasn't writing to App.Path in that case, but for the example it is OK. PS: I'm not copying here the functions IsNT, ShellVersion and GetAppDataFolder.

Did Win95 have a "MyDocuments" folder?? I'm probably wrong, but I can't help but remember that started with Win98.
