files appear to be unsupported or damaged
I'm synchronizing my LR files with my Hard Drive files. I get an Import Results page that says: Some import operations were not performed. The files appear to be unsupported or damaged. It then lists the files that could not be imported. When I look at the files, some are .CR2 (Canon RAW) files, some are .TIF files, and some are .PSD files.
I don't know when the problem originated, but I was able to open them earlier. There are hundreds of files that cannot be read.
Windows 7; LR 4.4; Photoshop CS6
Help will be very much appreciated
