Recover files in their original format extensions from readyboost

Needing to free up some memory, I transferred a directory containing a large number of files, mostly doc and docx but also some pdf and jpg, to a high-capacity usb memory stick.  Now I find that they have been stored in sfcache format, which I had never heard of.  When I try to open the directory in Word (I always accessed it in Word before, and right-clicked the non-doc files to select the program that opened them), I get a message that another program is using it.  Also when I insert the usb drive, there is no autorun popup.  I need to recover this material in the original formats, and I cannot find anything I can understand on how to do it.  

Files don't consume memory, they consume drive space

You shouldn't attempt to open files on a memory stick, they should be copied to a library location then opened there.

If you are that low of space, then you need to address that fundamental problem, possibly with a new hardrive, as its likely win will not be functioning correctly as it is

Start>Computer, what does it show for Hard Disk Drives?

for each drive/partition it will show xxGb free of xxGb
