The file will be in your incomplete folder in the library page in limewire. Just move the file from the incomplete folder into the folder you want it in.
Go to the LW library page and click on the incomplete folder and click the explore button. This will open the incomplete folder outside of LW and you can cut and paste it to your shared folder or wherever you want it. You can open your shared folder using the explore button also.
