Accessing a content archive

How can I access a copy of the content I "archived" on a PC (the DLC file)? I don't have the original content, and don't want to have to dump it to a media server, pull the drive, copy it off of the content partition. Seems over complicated for a few pics I want to hold on to. Oh, and I no longer have the master fixture the media was on either, so any "online" options are off the table ;-)

Any useful advise would be helpful.
