Permission problems with files, dragged into folder with padlock?

I have a external hardisk where i kept my files when suddenly there was this folder with a padlock appeared out of no where one day. but i just it there. Just now, I accidentally moved my folders into this folder with a padlock. Then when i reliased my mistake, I moved it back out. Nowm all the folders and sub folders have this permission problem and i can't access it. Videos, pictures and rar files, I can't access it. You can still access the folders because for the first time they'll ask "You currently have no permission to this folder.. and click continue to.." to i clicked continue. After that they give yet another message "You have been denied permission to access this folder.".Later there is this blue underlined word in the message which hyperlinks to the security tab of the folder. So chose continue again and chose administrator for access. AfterI close the tabs and all, I can access the folder but I can't access whatever contents in the folder. How can I fix this? I think the folder with the padlock did this to the files. Help from folder lock?

Right click on the folder with padlock--->properties--->goto security tab
click on advance on right bottom corner
goto owner tab ---|>edit--->and select your name as owner--->tick replace owner on subcontainer objects--->ok-->ok
