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: https://longpathtool.com/ However it isn’t free, the method above is.
