Using disc cleanup I decided to compress files to save space.  Of course, Windows did not tell me that doing so would slow down the system, so I answered, yes I will be glad to.  Anyway, I am trying to uncompress only those files that have been compressed.  I know how to go into Windows Explorer and manually click on each file, select properties,  uncheck compress, then apply .  But this is time consuming.  I can't get it to uncompress folders at all, just individual files.  Is it possible to click the C drive in my computer, select compress the entire drive, and then go back and uncheck the compress box?  Remember, I am only trying to uncompress certain files, not all of them, which are mainly the I386 ones.  The only other method I have found is at www.exodus-dev.com in which you run a utility that locates the files for you.  But I do not know how to create a batch file.  It locates the files, then a screen pops up and down without doing anything.
