Agreed...I think they have a television show for us called "Hoarders."  I've got a box of CDs and DVDs where I've burned off my purchase and download content for several years, and since very few of the files actually tell you what they are, it gets horribly confusing.  I make sure all my Rosity purchases, DAZ, RDNA, and other commercial sites downloads go into individual folders and then I burn those to DVD every six months or so.  This works especially well for me when it comes to characters.  Example: I have a folder specifically for my IllusionsDesigns characters, another for DAZ, etc.  That way I can remember which merchant to look for and sort from there.  I cannot, however, seem to find my V3/M3 download files...I put them somewhere "safe" and don't remember where.

I wish there were an indexing program that would generate an index to follow.
