Problem: Getting "Destination folder access denied. You need permission to perform this action" error message while trying to copy paste from local disk to SharePoint 2013 using explorer view?
If your source folder is customized with NTFS permissions, Try resetting those permissions and grant your account to FULL Control to your source folders and sub-folders beneath it in the local disk.
