Processing only processes those requiring changes, but setting the view doesn't affect this at all—it takes very little time to determine that a file doesn't need to be modified. Most of the time spent is in the actual renaming of the file in the operating system.

Logic followed, but no, it has nothing to do with the speed increase. The speed increase mainly resulted from removing Finder from the act of renaming files—we're now doing it at a lower level.

Let's see if I can ask this in a way that makes any sense at all...

First the setup:
Using the most current version of Name Mangler (v3.5) to perform Find & 
Replace function on a very large list of files (700k +) or some subset of 
that giant list.  After the list is built and my Find & Replace details are 
entered I can set the View Filter to "Show Modified Files" in order to see 
what's being changed.  For my purposes this list of modified files is 
rather small, something like 600 out of 700k files.  Being able to filter 
the view like this is absolutely essential for me to be able to confirm 
changes and such, so I'm glad that feature was added in v3.

The question:
My question has to do with processing.  Does "processing" or "renaming 
files" always process every file in the big list, or does it only process 
those requiring changes (as previewed when filtering the view to Show 
Modified Files)?

Follow my logic?  Does the question make sense?  Is this how speed has been 
increased between v2 and v3?

Thanks.
