I was trying to move a file from one folder to another. This was a frequently used folder. I had done this operation a thousand times before. Suddenly I got this error message:
Destination Folder Access DeniedA search led to the suggestion that, in Windows Explorer, I should right-click on the folder and go to Properties > Security tab > Advanced > Owner tab > Edit > select Administrator (since that was who I wanted to own the folder, though that was *already* who owned it) > Apply > OK. That didn't work. Some remarks indicated that this could be a digital rights management issue, in the case of a music file, but this was just a PDF. It was, however, a PDF created by Sumatra PDF, in an attempt to remove security from the PDF so that I could run OCR on it. It seemed I should have used Foxit instead. Anyway, I went back into Properties > Security tab > Advanced > Everyone > Change Permissions > Everyone (check both boxes) > Apply > OK. That didn't do it either. I moved everything out of the folder, deleted it, put its former contents into a new folder, and was able to work normally. No explanation.
You need permission to perform this action
