Compare contents of directories

I am ne to Opus and it is a bit overwhelming to be sure. I have 2 directories of files and I am trying to find out how to compare the contents of these and to display the files that are present in the source directory that are NOT present in the other?

A button with..

Select ALL
Select SOURCETODEST DESELECTNOMATCH
Select DESTTOSOURCE DESELECTNOMATCH
Select INVERT

..should do the trick.

The code shown above will Select non matching files. You can use the HIDEUNSEL option to filter out matching files from the display if that's what you want.

If you want to compare a directory including subdirectories, use Tools -> Synchronize, and set the mode to One Way Copy.
