"PCMag reports that Googles Desktop search may be finding things in encrypted files and folders."
These are those files made encrypted by MS Office and XP. All you see is people blaming Google for showing results from encrypted files but no-one seems to be picking up on the idea that if Google can get into the files without the password then well anyone can if they reverse engineer the way Google does it.
I would like to know how many people think that it's googles fault or if it's MS's fault for making their encryption so crappy.
Is this due to Googles reverse engineering technology or are their spiders simply (or not so simply) so strong that they are able to delve into these files? Or both?

And how effective are the 'robots.txt' files, taken the above into consideration?
