Solved: Folder locked itself

I am currently copying about 250Gb of files from an external disc to a folder called Recovery on my C internal drive.

After copying about 100gb taking about 21 hours the folder displays just turned off on the screen and the copying stopped.

The problem is the file called Recovery has locked itself somehow and I can't access it.

When I click on the file name it opens a window showing one folder with a string of numbers and letter as a name and within that there arre two files called boot.sdi and winre.wim.

Can you please advise how I can get into this folder?

Thanks.
