Abstract: A file download manager automatically controls how and where downloaded files are stored. A method for use in downloading a file includes establishing communications between a network site and a computer that is visiting the network site, automatically detecting whether a device capable of receiving files is connected to the computer, automatically determining a location in the device where a file may be stored, and automatically downloading a file from the network site to the computer and sending the downloaded file to the device to be stored at the determined location in the device. A computer readable storage medium stores one or more computer programs adapted to cause a processor based system to execute these steps.

Abstract: The present invention provides novel lipophilic drug derivatives which are capable of being formulated in liposomes or micelles. These drug derivatives are known therapeutic agents which are covalently attached to a fatty acid chain of a phospholipid, glyceride, ceramide or 1,2-diacyloxypropane-3-amine. The linkage between the therapeutic agent and the lipid is one which can be cleaved in vivo, allowing the therapeutic agent to be separated from the micellar or liposomal formulation.
