Guess I'm just going to be misunderstood. I don't want just the TIFF files exported. I want the TIFF files (not their duplicate CR2 files) and all the CR2 files that that did not go to PS to all be exported in one go.
If out of 100 files I send one file to PS and it comes back. For example it was the 50th file in the bunch. I want 100 jpgs exported. 1-49 are from the CR2's, #50 is the TIFF, 51-100 are the other CR2's. I want them numbered 1 to 100 at export and that TIFF will be a Jpeg numbered 50 in that sequence. Sometimes there are 10 TIFF's out of 100 files.
I tried the filter as suggested. All I got where TIFF's.
No idea where you are getting DUPLICATE CR2 files from. But if you want to export ALL the UN-FLAGGED images (CR2 and TIFF) that are in a folder then just filter them by flag status.
