A solution for mac :
You can choose your file in a window, and the data are imported in data

Thanks, Markus.  When I select the file in the Finder and use "cmd+i", I get an Info box.  The box does have a "Name & Extension" component containing the text string "sampledata.xlsx" which I can copy and paste.  The Info box also has a "General" component with other information about the file including "Where: /Users/store/Desktop" and I also can copy Where's text string.

In Mathematica, I tried
  data = Import["/Users/store/Desktop/sampledata.xlsx", {"Data", 1}]
which worked perfectly.  I also tried
  data = Import["sampledata.xlsx",
Path -> "/Users/store/Desktop", {"Data", 1}]
giving me "Import::argt: Import called with 3 arguments; 1 or 2 arguments are expected."  I got the same error with
  data = Import["sampledata.xlsx",
Path -> "/Users/store/Desktop/", {"Data", 1}]
 
I'd prefer to use the Path option, but I obviously don't know the syntax Mathematica requires for a path specification.

Hi Harry

Try it like this:
File path under OSX is available with short-key “cmd+i". In the same pop up window you can also copy the file name.
