I would like to generate a list of files that are non-dupes (ignore content) but with a certain attribute such as the same extension (for example .RAW)

Right now when I engage the 'Ignore Content' selection, I get a message when the scan is started that says I must specify a DUPE Criteria.

DuplicateCleaner has such a rich set of features, I can't believe that there is not some way to do this. Unfortunately I have not discovered it so far.

Any help would be most appreciated.

There is currently no way with Duplicate Cleaner to set up a scan with file extension as the only duplicate criteria.
This is partly a safety feature - grouping files as duplicates just by their extension means that the files themselves could be unique, and could result in deletion by the unwary user.

The search feature in Windows Explorer (eg *.raw) can do this job, and the found files can then be deleted or moved from the resulting list.

Everything has a "dupe:" function.

So a search like:
Will very quickly find non-duplicate file (names*) *.raw.
(*Everything only deals with names, not content.)
("dupe:" is the function. "!" is a NOT function.)

How does dupe: work

Non -duplicate file listing

Many tks for the heads-up re: 'everything' : will start experimenting w it asap. Was hoping 'duplicate cleaner' had something as you have described built-in, but alas, that does not seem to be the case.

Again thank you for your expertise and the great suggestion.
