    Lightroom "unable to prepare the selected file"


      Hi all,

      I know this has been asked a few times so apologies for repeating the question but I don't seem to be able to find an answer that resolves the problem.

      My photographs are stored on a NAS drive which is automatically mounted at boot time and I can quite happily open them in lightroom and make edits but if I try to open them in a plug-in like Nik Silver Efex I get an error along the lines of :


      Lightroom was unable to prepare the selected file at /Volumes/Photography/Lightroom photos/2016/Berwick 2016/DSC_2471.NEF for editing.


      I assume it is a permission issue on the drive but when I look at the filesystem permissions they seem ok to me (Note the folder name "Berwick 2016" is the same as in the error message above) :

      If I look in the folder after I get the error I can see that Lightroom tried to create a copy of the file for editing but it's zero kb in size :

      Any help would be gratefully received.


      Thanks and regards,
