  2. setting default app by file type

    How do you set the Kindle app to be defaulted to .mobi file type? I don't find the .mobi file type listed as a file type.

  3. app default setting by file type

    Hi Richard,

    We understand that you're having issues with the default file app association on your computer. To assist you with your concern, you may refer to the steps below on how to change the default setting of your application:

    • In Search Windows textbox, search for choose a default app for each type of file and set .PDF and any other file extensions to point to your choice for default
      programs. Do not use Adobe Reader to set the association.
    • Navigate to %systemroot%\system32 and locate the OEMDefaultAssociations.xml file. Make a backup of it just in case.
    • Open the OEMDefaultAssociations.xml file and keep it open using
      Notepad.exe.
    • Open PowerShell or CMD and run it as Administrator.
    • Enter the following: Dism /Online /Export-DefaultAppAssociations:C:\AppAssoc.xml
    • Open C:\AppAssoc.xml with Notepad.exe
    • Copy the entire contents of AppAssoc.xml and replace the entire content of OEMDefaultAssociations.xml.
    • Save OEMDefaultAssociations.xml.
    • Delete C:\AppAssoc.xml (optional).

    After doing the steps, you may now change the default file app association for opening .pdf.

    Do update us with the outcome and if you need further assistance.

    Regards.

    Hi, first, what do you see if you go to Settings here?

    You should have a list of registered file types- in your case, expect them to be limited to the defaults that are available when you install Windows (+ any others created by programs you may have installed at some point).

    You have at least two difficulties.
    a. Your portable programs won't be registered to handle any file types.
    b. A portable program that handles file types not available on your system can't be assigned to them - as they don't exist.
    (Imagine a portable office program - doc and docx don't exists as file types until you install a handler).

    If the file type exists, then you may be able to rt click it, Open With and browse to your portable program.
    However, as that program is not registered to handle it, I'm not sure quite what you'll end up with (see rtf example below, and consider the effect of assigning an unregistered program to it).

    If it doesn't, you will have to create it, and all that goes with it.

    You may find this free program helpful:

    Also this one (note: I've shown the rtf extension - look at what is needed to handle it- and the program's parameters)
