OS X 10.10 Copy / Paste Source file count does not match destination file count
Is it possible, that there are hidden files in the source folder?

You could use this shortcut in Finder to switch between showing/hiding hidden files.


  CMD + SHIFT + .


If you want to make sure to copy the whole content anyway, open Terminal.app and enter


  cp -pr /path/to/source /path/to/destination


After typing "cp -pr " in Terminal, you can drag&amp;drop the folder names vom Finder window to Terminal window.
