I guess you're refering to sending files to a particular person such as a friend or relative.
You can direct connect or another way is to use magnet links.
For
Direct Connect, see:
How to Direct Connect, Browse & Chat & keep in mind your & their firewall need to be properly configured for LW's full access otherwise you will have some problems using DC. To find out do this test:
Bug Report instructions & sample image Is the result True/False? If false then you need to configure your firewall (only need one firewall as 2 can interfere with each other.) Remember XP has its own firewall. Instructions:

For
Magnet links (See image below) , this is also a very effective method of sending particular files to other people. Go to your LW Library window, select the file you wish to send, Right-click (Control-click for mac users) & select Magnet Details for ... & your browser will open & give you the details of the magnet link. Use the link opposite the 'Magnet' word. Then copy & paste this link address & email or send it via chat to your friend. They will need do have LW open, but, they can copy & paste this magnet link address into their browser & the browser will send the details to their LW which will immediately start to downld the file. Of course you both should have LW open at that time so they can access your LW shared files. Once they are connected, they & you can browse eachother's files. Remember to browse someone it's best to have Chat enabled.
Hope this helps.
