Moving a file, access denied

I'm the administrator and only user of my PC, and I'm trying to copy a large .rar into a normal folder, but 1 of the files doesn't want to move, it says "Destination Folder Access Denied, you need permission to perform this operation." I checked the security and made sure my account has full control over the folder and even the folder that it's inside, but still can't move the exact file over.

I first moved them all at once, and it's like the 3rd to last file, so that file and the last 2 didn't move. So I unpacked the .rar somewhere else then tried again, same thing, every file except the last 3, so I moved each of the 3 individually and the single file still wouldn't move, but the other 2 moved fine, and the mod doesn't work without the file at all.
