No Open Button

Hi folks. I am having trouble unbricking a cell phone. I am using Win7 Pro. When I open the folder with the files that need to be added to Odin 3, there is no open button at the bottom of the page, so that when I click on one of the files I can't open so it will insert into Odin. I don't know why there is no open button. When I went into properties to check the files, they were blocked so I remedied that. I thought that would fix the problem, but, of course, it didn't which is why I am here. Any help would be much appreciated.Thanks.
