In fact, if a file we can’t delete it, that our mentality is very bed. I am new here but I can give a small suggestion. Please note that, restart your computer than go to the task manager and click in the processor and please end some. Then you may be able to delete it. Moreover Long Path Tool helped me in this situation, so at lest you can download “Long Path Tool" for delete this file. Thank you so much.
You can explore your disk by a third party tool. Once I can't see the detail information, like the files' list, I tried MiniAide Magic Partiiton Tool, its "Explore Partition" helped me. In addition, it is also a powerful partition management tool, which can help you manage your disks/partitions. You can also have a try. http://www.magic-partition.com/?20
