New user - Need some simple workflow advice...

I am a new user of Capture One 7. I have a (hopefully) very simple question: apologies in advance if the question is already answered somewhere else, I've tried searching for it and not found the answer yet - but I may just be hopeless at working out what the right terms to search for are.

Here is what I am doing...

• I am importing images into catalogs, and storing the originals in folders on a drive connected to my Mac computer. {/*]


• I then go through the images and identify the best ones [/*:308b9g92]
  
• I work on the images selected and generate some selected images for output[/*:308b9g92]
  
• I then want to delete the unwanted images, including the source image - but when I delete inside the Catalog it does not delete the original image.


• I know I could go to the finder and delete images directly from the folders they are in (after they are deleted from Capture One catalog) but I don't know how I would be able to tell in Finder which images are the ones to be deleted.

I perhaps could do this more easily if I used a Session for the initial working on a batch of images, and then import just the selected images (original and variants) to the catalog - but I'm not clear how to do this.

So, if anyone has any suggestions about how I could do what I describe above, I'd be most grateful.

Thanks a lot in advance for helping.
