SamR 0 Report post Posted June 26, 2019 I am trying to copy a PDF from an encrypted DVD that is 174MB. I gain access to the file no problem. When I try to copy the PDF (or even open it), I receive the error code: 0x400D00DF. I understand this is a windows code. I went into the registry and modified the WebClient\Parameters\FileSizeLimitIn... (a solution I've seen in some other places). That did not help the problem. Any suggestions?
