New Win 7 PC. Need old sonar files. I put instruments where they go, sonar cant find them.

For some reason with Windows 7, it seems like it doesn't really show you the entire directory tree? I put my home made SFZ instruments in the sonar/samples file where it should be, but sonar tells me it can't find the instruments. I have 8.5 Producer, and 7.0 Home Studio. Some of these songs were made in Home Studio, and I'd like to be able to access them. All of the data is still there, but I can't remember which instruments I used. I can tell drums by sight, but the rest are tough (midi). I can't find a way to go in the track and search for the file location. It doesn't look like it's in global options? I need to find a way to set this directory structure up exactly like it was in Windows XP. Any ideas? TIA      FJ
