Starting a new thread with this problem.
When I import direct from the card into LR I get the following message window:
Some import operations were not performed:
The files could not be copied to the backup location.
The following files were imported but could not be renamed.
There is also a drop down arrow that lists all the file numbers.
If I try to open one of the files in the develop module I get the following message:
'file is missing or offline'
All the files and the associated folder have a question mark.
If I download the files to my HD first then import to LR there is no problem.
