I recently bought a new Win10 pc. Then I tried to access the folders I had saved in an external hard drive, which I used to use with Windows 7. To begin with I wasn't able to access specific folders- a message would come up saying "Access Denied". Somehow while I was playing with the permissions I managed to get into the folder but then the contents (videos) wouldnt play.
I have tried gaining ownership of the folder via the properties, but this hasn't fixed the problem. I have also made sure that I have admin permissions.
Does anyone have any idea of why this is happening and how I can fix it?
