I thought that I had downloaded soundtrack music, but where did the music files go?
Do you use the Firefox browser? If so, you should know that they have now implemented a security
update to restrict access to downloads of files which are not commonly downloaded. Caught up in the current wave of paranoia, the Firefox people have decided to quarantine files which have not achieved their threshold of popularity. There is a little yellow dot in the top right corner of the Firefox browser accompanying download completion which (when clicked upon) will explain the policy and your available actions (open OR delete) ...
If you look in your download folder you may see the music track files renamed with the
final extension ".part". If you just rename the file without this extension ".part", they can still be opened and used with your regular applications.
These days, there seems to be a push to limit free transfer of files or information which does not originate from "authorized" sources. Under the guise of security, the field of available information sources is being limited. For further information on this troubling trend, read Jaron Lanier's excellent books "You Are Not a Gadget" and "Who Owns The Future?".
