External application invocation

[ghost]

from GS thread:

What would you think about a way to pass selected or highlighted files to Windows as a command line for external processing? For example, Scooter Software's Beyond Compare (BC) program lets you play 2 MP3s side by side so you can make auditory comparisons -- this is a really powerful way to compare audio content. If I was able to select very similar files from DGME's results list for further examination outside of DGME it would really streamline the duplicate finding process.

Once the external program returns control to DGME, DGME would refresh those specific entries in its list in case any properties of the files have changed. A configurable command line would tell BC to load the two files for comparison in the above example. There could even be a list of programs defined by the user for regular use. Maybe it could come with some example entries to get people started.
