Recently updated to InDesign CC 2015 (with the rest of the suite) and when I package some artwork, the links to Illustrator & jpegs are in the 'Links' folder, but all say 'zero bytes' in the filesize.
If you open the packaged .indd file the links don't show as missing or broken, but if you try to amend them it says they are '...an unkown format and cannot be opened'.
I'm on OSX 10.9.4, I have tried packaging from the network, and locally, but the same thing happens.
Video of problem.
Any help would be gratefully received.
Have you tried repairing permissions with Disk Utility and try it all over again?
Did you find a solution with zero bytes file size in links folder ?
I have the same issue with netatalk Linux server with Netatalk 3.1.7 version.
But It's working with Netatalk 2.2.
