Have a look at "Sample App: Clipboard": Select some files, then "Copy Selected Files". Paste the clipboard contents, you will see something like:
D:\Data\TESTBILDER IMatch\Test 03\008-1.JPG
D:\Data\TESTBILDER IMatch\Test 03\008-3.JPG
D:\Data\TESTBILDER IMatch\Test 03\008-4.JPG
D:\Data\TESTBILDER IMatch\Test 03\008-4-1.JPG
Or just select the files in the file window, use "Copy", and paste the pathes.
[EDIT]: Sorry, did not read your post correctly. You want only filenames, without pathes. For that, my hints do not work.
