    Change default application back to "unknown" for file type of .dst


    I some how changed file type .dst to open with Corel Draw. I need to change it back to unknown application. I am operating with Windows 10. I have tried going through control panel/default programs/ however it forces me to pick an application, no option for "unknown application".

    Hello, and welcome to Ten Forums.

    If you like, you can download and merge the .reg file below to unassociate .dst files.

    Sorry to be helpless...I ran the file you attached Unassociate_dst.reg above. How do I "merge" the file to unassociate the .dst files? Thank you!

    No problem. You can double click on the .reg file and approve the prompts to merge it.
