    Windows 7: Change back to "Unknown Application"


    I accidentally set TMP file from location

    (C:\Users\Personal\AppData\Local\Google\Chrome\User Data\Default\Pepper Data\Shockwave Flash)

    "open with" to vlc player
    The files were originally designated as being opened with an "unknown application". I can set these files to be opened by default with any program, but as it is not on the list how do I change it back to open with "unknown application"?

    I know it's no big deal and it can stay that way without any problem , but things like that can annoy me at times

    Any advice appreciated , thanks.

    Hello Nitu, and welcome to Seven Forums.

    If you like, you could download and merge the .reg file for the listed tmp option in the tutorial below to restore it's default association.

    Default File Type Associations - Restore

    Hope this helps, :)
