Answer to error code 8062
I believe I solved this one.
When you have some items that needs to be downloaded from the cloud in the folder you want to copy to a harddrive, then you will get this error.
Once all the items have been downloaded(in other words, there is no longer a little cloud icon when in list view’ then the folder or files will copy as per normal. boom.
