and it just returns to the command prompt without any message or output.
If I type the above command without the -c and *.NEF at the end, it starts the GUI interface, so the path to the executable is correct.
When I get the above to work, I then want to take the next step and put it in a FOR loop as shown below to convert all my NEF files in all my folders (below current folder), but I first should get the basic command to work.
for /R %f in (*.NEF) do "c:\Program Files\Adobe\Adobe DNG Converter\Adobe DNG Converter.exe" -cr4.6 -dDNGexport %f
I wrote a Bridge script to convert files using DNG Converter via command line. It took a LOT of finagling (Windows sucks, and I use Powershell to hide the stupid command window which made things even more fun) but it does now work.
