cannot open in PSCC

[desertdog]

Some files in LrC contain an explanation point stating that the files cannot be used because the originals could not be found. Obviously there is "a" file so how can I transfer what I am seeing to PSCC?

The explanation point is a warning when Lightroom can no longer find the photos at their last known location.

Here you'll find informations how you can fix it: https://www.lightroomqueen.com/lightroom-photos-missing-fix/

Obviously there is "a" file so how can I transfer what I am seeing to PSCC?

In this case there's is no file. What you see in LR is a preview that was generated when the picture was imported.

I you wish to open a picture in Photoshop you have to fixup the missing photo warning first so thatLightroom can access the original photo.

The file is not where Lightroom Classic expects it to be. Somehow, the file was moved or renamed or deleted outside of Lightroom Classic. (Or the folders that contain the file were renamed or moved or deleted)

So you need to find the file on your hard disk using your operating system. Once you know where the file is, and its name, then you can reconnect Lightroom Classic to the file and then everything should work as expected.
