Not really. If you make a link (soft or hard) you get one file/dir with
two names and/or locations. Any changes made through the link will be in
fact done to the file/dir itself. If you change one copy of a file/dir
the other copy will not change and the space occupied is (almost)
double.

P.S.If you knew what symlinks/hardlinks are but just didn't know what
ln does than just ignore the above :)
