> You can also use Bridge to show the filetype
I am using LR, so Bridge is not involved in the process at all and, in fact, I really never used Bridge.
> let ius know the history of this file
No complex history. It is a raw image taken a couple of weeks ago on a camping trip. I copied all of the images from that trip to my external usb 3 drive when we returned from the trip and am accessing them from there via Lightroom. I then send the image as a smart object to Photoshop, and that is all.
Nothing complex at all.
Bridge works with any files from lightroom or any program, to tell you what the file type is. NEF is the Nikon camera raw format.
How did you get "OLY0003-01" out of your camera without an file name extension? Did you use software to extract the image from your camera, or maybe a compact flash reader to drag copy.
What you posted earlier seems to have an issue, the file is named .psd but the file type is .tif.

Looking over your situation with more information i think you would be better keep the finder setting off, that I originally suggested to actually match my screenshot, and manually adding the file extension at the end as per norman.sanders suggestion. That finder setting on causes alot of trouble in the end being on, and is a long and convoluted explanation between manually tags in the filename, and showing a tag pulled from the resource fork part of the file.
