You can unshare if that is what you really want to do, but that defeats the purpose of LimeWire and p2p applications in general.

In LW tools>options>sharing ---- shared folders --- you can highlight the folder then select remove. You can repeat this process for each shared folder. Download sharing --- uncheck this box. Then click apply then okay.

In LW tools>options>uploads>basic ---- partial files ---- allow partial file sharing --- uncheck this box --- click apply then okay.

You can also unshare folders or files from the library tab. Highlight the folder or file you would like to unshare then right mouse click and click unshare. **Warning** Do not click delete if you do your files are gone and you will need a file recovery program to retrieve them.
