Go to the LW Library window. Ignore the incomplete & Saved Files folder. But all other folders within there are being shared. Shared files are in black. If they're not yet being shared then they will be red in colour. You can see this when you 1st open LW. Anyway, click on the folders to see which files are being shared. Look to the far right under the upload & hits columns & this will tell you which ones have been uploaded or which ones been found in other people's searches.

To add more files to share. Whilst in the LW Lib window, go to menu File>Add Folder to share. The other way is to go to Tools>Options>Sharing & press the add button & select the new folder. Then press apply after adding.
