You can use SetDirectory. But of course you still have to give the
path. A method that I find very useful especially if I am working with
different operating systems is to use the experimental function called
FileBrowse:. Suppose I  have a notebook open and I need to read some
data from a file  buried deep in one of my folders. I type in  and
evaluate

Experimental`FileBrowse[False]

You are then present with a dialog box that allows you to browse for a
file. Once you have found the file  select Open and a string 
representing the path to that file is pasted into the Notebook. I can
then copy that string into the required function e.g. Get or Read etc.
If I want to set the directory for a particular file I can paste the
path with the file name deleted into SetDirectory.

I find this function very handy and helpful for teaching students to
read files into Mathematica no matter what operating system they are
familiar with.

Cheers,

Brian
