Torrent   Dico Tools
A method of making data available for download over the internet, where the recipient of data is expected to make the data available to others for download from their PC, rather than all users downloading from a central server.

A few TSRs are essential, but many are installed automatically by a particular application just to improve its own performance, with no thought for anything else you may be doing, and may actually have a negative impact on everything else. Usually (but not always) launched from the StartUp folder in the Windows Start Menu.
