How do I find songs once downloaded? Not listed in library. HELP!

And where would I find the 'saved' folder?

Well, since you asked so nicely

When running LimeWire, go to: Tools > Options > Saving

That will tell you the location of your "Download To" Folder. You can change it's location if you want. And you can add it to your Shared items by going to: Tools > Options > Sharing and clicking on "Add" and choose that folder.

Hope this helps.

the loacation that the downloaded files are saved to by default is C:\Program Files\limewire\shared. You can change that in the tools-> options area of LW if you want to. But whatever the name of the folder is, it's just a mirror of the folder on your HD. So you will find all your downloads in that folder using Windows Explorer.
