Locked File Access

I recently decided to move my archived video and photo files, from a small (250GB) drive to a larger (500GB) drive as the smaller one is maxed out. However when I tried to move them, I got an error message "You need permission from 'Doug' to access this file" (or similar). In review of the source files, I see the majority of them have a padlock icon in front of them. I checked the parent file and I ('Doug') am the owner of the entire drive, all folders and all files, with total control and permissions over all of them. Yet I cannot move them, open them, rename them, or in any way utilize these archived files.

I did not ask for any encryption on the drive (which is also open for sharing with 'everyone') I have been using this drive since many previous OS setups, and other computers, since Vista, and never had problems accessing them before. I see in looking at the target drive, that all files that did not have the padlock, were moved to the new drive. I am thinking that these files may be encrypted with the old EFS(?) security, but not sure as I have never used it, at least not deliberately, but if I did it would have been under the same owner name, and passwords. I am hoping by this time in the tech evolution, that there is a workaround as some of these files are digitized 30-40 year old videos and photos, with no originals left, so I need to get these back. I am talking thousands of files!
