    can't identify or open unknown file type


    I have run across some video files that, although tagged as MP4, cannot be played on my VLC player, KM player, or Windows Media Player. File Identifier (File Identifier - Identify unknown files instantly) shows info as attached. Please tell me how to deal with these files so they are usable on my PC.

    opening .dds files with gimp

    Simply, HOW? I got the DDS plugin but the POS wont open DDS files still. Can someone give me a step-by-step rundown of how to install the DDS plugin for gimp so I know if I'm missing something?

    Change file type association back to unknown

    Here is a working solution to set a file association back to unknown, it looks a long process, but it is fairly simple

    • Make sure you can see file extensions - In Windows File Explorer, on the View Ribbon check the 'File Name Extensions' box
    • Close Windows File Explorer
    • On your Desktop, right click and select 'New' - Text Document
    • Name the file xxx.bat - make sure to remove the .txt and replace it with .bat
    • Right click any .gp4 file, select 'Open With' - Choose Another App'
    • IMPORTANT - Check the box marked 'Always use this app to open .gp4 files'
    • Scroll to to bottom of the list, click 'Choose another App'
    • Scroll to the bottom of this list and select 'Look for another app on this PC'
    • Navigate to the file you created on your Desktop (xxx.bat) and click open
    • You will probably get an error trying to open the file - this is OK
    • IMPORTANT - Delete xxx.bat from your desktop

    Now the file association will be set back to unknown . . .
