SDHC(E:)\DCIM\100Nikon is the SD-card in your camera or the SD card in your reader while it was connected with the laptop. It's not on your laptop itself, and apparently they weren't transferred either.
In the future, better copy them to a good place on your c:-drive (say, you're My Pictures folder) and include them in your regular backup also (which could be Onedrive, of course). Then the chance that you'll ever lose them is quite small.
I have Nikon Coolpix S3300 camera. I uploaded to my laptop about 15 pics into File Explorer, and OneDrive with my USB card reader. I saw all the pics inside the laptop and was satisfied, so I removed the USB card reader from the laptop, removed the card from the USB reader and put it back in the camera, then deleted those pics from memory to have more room.
When I proceeded to send the pics to my family.....I couldn't find them anywhere! The places where I found them the first time were: SDHC(E:); DCIM; 100Nikon but now these disappeared also. I spent almost all day searching all over and no luck. I tried to search the Microsoft Edge as I saw its icon once in my taskbar, but couldn't find where their photos page was.
I know I should've never deleted them from the camera, but they were already transferred to my laptop. I beg someone to please help me find those pictures? Thanks ever so much! ![]()
