Hi Kirk,
Many thanks for your reply!
Firstly I must apologise for not being clearer regarding my workflow! I don't use explore to download my images, I use Canon Image and Zoom Browser; it's a programme I've been using for years and have become familiar with.
RAW file folders that are already in my library are displaying normally in PM, the issue has only occurred on my latest downloads and the upgraded version of PM!
I have just re-installed PM and added another RAW image folder, the problem appears to have resolved itself!
I'm just wondering if there is something in the PM preferences default that caused this in the first place?
I think I will have a go at changing my workflow and start using the PM ingest command instead, I'm afraid I'm a bit stuck in my ways as have been using the same workflow for more years than I care to mention!
Once again, thank you for taking the time to reply, especially as this is my first post on this forum!
Chris
