Load saved Sources
This will save selected number Of The Best Sources Including Source Exchange, to a subfolder in your temp directory under eMule called Saved Sources. Each file you are downloading will have a file in there. Also these files can read in a text editor such as notepad. There will be an ed2k link in there incase you lose a download to use. This will help the next time that you start eMule this will help you get your downloads started faster again by loading the saved sources.
After some time the saved sources will lose meaning since sources go off-line after some time. (a timestamp is added in the saved source)

You can have automatic SLS (Load at start)
And Manual SLS (Right click on a file: you can Save or Load source)
