Cannot import / convert RAW files into Lightroom in Windows 10

Trying to import RAW files from my Nikon D7200 into Lightroom 6 and convert to DNG files on my Windows 10 Surface Pro 3. It fails every time with the error "Cannot read files" even though the OS can clearly read them and display thumbnails.

This happens even when I copy the RAW files from the camera to the computer and try to import from there, so it's not the source.

I have a lot of people waiting to see class reunion photos :-).

The issue is your destination of the Copy Import operation. The Copy phase is failing so the Import phase doesn't have any files to read.

Check the destination at the right of the Import panel and make sure it is what you intend and it has read/write permissions for non-administrator users on the computer.

Windows 10 either resets permissions or changes programs to a more restrictive context or both.

Hi Steve, thanks for the speedy reply.

Saving the output to a different folder did fix the problem - but raised another question. The original destination is a OneDrive folder, which worked perfectly with Lightroom on 8.1. Of course the OneDrive sync engine and replication model changed with 10, so it sounds like there's some folder locking mechanism in OneDrive that's preventing Lightroom from writing out the files. Even though I've not noticed any problems myself.

Win 10 tries to make OneDrive more efficient by not copying everything by default. From what I've read on here, you can right-click the LR shortcut, select Properties, go to the Compatibility tab and enable OneDrive compatibility. It's a program-by-program settings, now.
