Some time ago I posted a similar question.
I found Bob Hanlon's suggestion, use the command Input/Get  File Path, very

Just overlay the two plots.

plt1 = ListPlot[{0,2,4,9,16,25},
          DisplayFunction -> Identity];

plt2 = ListPlot[{0,2,4,9,16,25},
          PlotJoined -> True,
          DisplayFunction -> Identity];

Show[{plt1, plt2}, DisplayFunction-> $DisplayFunction];

For Path names use the command

          Input, Get File Path ...

and select file from browser.

Subject: [mg17177]  [mg17129] Dialog for selecting a file to be read

I often load data files to be processed in Mathematica and it is quite
cumbersome that I have to explicitly specify the path and the
filename every time. I would rather pick from a list in a dialog window.

As far as I know there is no simple way to invoke the operating system's
file open dialog from Mathematica. Has anyone come up with a solution?

I can imagine that a small external program (maybe linked via mathlink or
called with <<"! ) can do the job.
Another possibility would be a fancy construct (maybe as a button) using
Mathematica Commands FileNames[], SetDirectory[], etc.

If you know of anything related please let me know!

Cheers, Martin.
