Hello,
1) Copying of any file larger than 4 GB is not supported, but gives no error message. It just doesn't work.
I believe that is the limit but a change is being considered.
2) Copying of large amount of files, will slow to a stop and never finish.
Whats 'large'?
If you are talking about 10s of thousands of files in one copy, that is a tremendous amout of seeking / read / write over any medium. In those cases, perhaps a direct share (to a NAS) is a more practical option.
