1. Long Path Fixer: ( httpss://goo.gl/jJHBRD ) It's a portable app so you can put it on a key ring and take it anywhere. I love portable apps and have a drive on my key ring that has emergency repair apps, and a plethora of other portable, useful stuff. Operation is pretty straightforward. Launch the app and choose which file(s) or folder(s) you want to move, copy, or delete and choose where to move or copy them to.
On the same page, and working in conjunction with Long Path Fixer, is yet another small, portable app called LockHunter. I'd suggest you download it as well. Lock Hunter will "unlock" files that are in use by windows or any other program making them ready to move. ( httpss://goo.gl/qDFEsv )
