The file name(s) would be too long for the destination folder

The quickest fix for this, especially if you are needing to simply migrate a lot of folders from one place to another is to map a drive to the drilled down folder.
What I would do is browse to the hidden share path and copy it to your clipboard.
Then browse to “Computer” or “My Computer” and click on Map Network Drive. Depending on your OS it might appear under the tools menu.
Then simply paste your long path and hit Finish.
Now you will be able to copy the files/folders into this location without receiving that error.
There also is a great tool called “Long Path Tool” that works great to fix this: http://longpathtool.com/However it isn’t free, the method above is.
Thank you Colin Albright for the comment below. Yes, you can also use 7-zip or any zip utility to fix the problem. Sometimes on single files, this could be a better and faster solution. Just zip the folder up, and your good to go.
