I don’t know if it’s good or bad, but I like when the files I’m working with are in the working directory (so instead of using pathnames to my files I can just type filename or ./filename). But to avoid copying data and wasting space, symbolic links are the way to go. The command for that is:
ln -s target_file sym_link,
where -s stands for “symbolic” (just ln would create a hard link)
