its only my .mkv files everything else works perfectly.

I use the directory listing function in IIS to upload a bunch of files for friends and family to easy access and download.

 

My problem is that .mkv files it lists but when you click it i get a 'The page cannot be found'.

 

Ive tried relocating the file and renaming it but i get the same error each time. Why does it do this? Its only my .mkv files everything else works perfectly.

 

Thanks in advance.
