Every now and then I REALLY need to replace some text with some other text in a whole series of directories.  This is especially true when working with MOC course, with LOTS of references to a server name in all sorts of solutions. 

There's a GREAT tool that does simple search and replace, through any number or type of files, regardless of directory depth called ReplaceEm.  And, it's FREE!  The developer just wants you think of FitSoftware when you need some software development done.  Download it here.
