It's a PSD file.
That's a photoshop document. Not so strange for a photoshop newsgroup.

To the OP, there are dozens of different ways you could do this.
Personally, the method I would use is as follows...

Set up a new layer in your image.
Now using the rectanguelar marquee tool, draw a rectangular selection.
Next click Select > Modify > Smooth, and enter a number that corrsponds to
the number of pixels you want your radius to be. Click on Okay.
Now your selection will have radiused corners. Use the paint-bucket to flood
it with whatever colour you want your line to be.
Next click Select > Modify > Contract, and enter a number that corrsponds to
the number of pixels width you want your line to be. Click on Okay.
Now hit the delete key on your keyboard.
Lastly, click Select > Deselect.

That will replicate the effect you have shown us, but this is only one of a
dozen or so different ways of doing the same job.
You'll get loads of other answers suggesting different methods. Each one as
valid as the last one. The trick is to try them all and find the one that
you find easiest.

Good luck.
