I have a pdf file without the '.pdf' extension in the name. When I try to open the file with 'Evince Document Viewer' I get 'Unable to open document "name" Error opening file: permission denied' - however, if I add the '.pdf' extension to the name I am able to open the document. I am sure I was able to open the file previously regardless of extension, does anyone know what may have caused this? Its Evince because Gimp can open the pdf regardless of extension.
Thanks!
