Answer  up vote 3 down vote accepted  There is a decent page on
Microsoft's site explaining the pros and cons.  Basically, there
is a performance penalty so don't use it on files and folders
you access often. A small delay incurred infrequently is
probably ok for most people.  I suppose that if you are getting
desparate for disk space then you may be willing to accept the
performance hit and use it for more frequently used stuff.  The
actual performance hit will depend very much on your machine, if
you are getting short of space try it, otherwise I wouldn't
bother.  share|improve this answer Agreed: With today's large
