The following method creates a custom mime type and file association manually.  This is useful if your desktop does not have a mime type/file association editor installed.  In this example, a fictional multimedia application 'foobar' will be associated with all '*.foo' files.  This will be done a per user basis (as opposed to system-wide).
* First, create the file {{ic|~/.local/share/mime/packages/application-x-foobar.xml}}:
$ mkdir -p ~/.local/share/mime/packages
$ cd ~/.local/share/mime/packages
$ touch application-x-foobar.xml
* Then edit {{ic|~/.local/share/mime/packages/application-x-foobar.xml}} and add this text:
<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
<mime-type type="application/x-foobar">
<comment>foo file</comment>
<icon name="application-x-foobar"/>
<glob pattern="*.foo"/>
Note that you can use any icon, including one for another application.
* Next, edit or create the file {{ic|~/.local/share/applications/foobar.desktop}} to contain something like:
[Desktop Entry]
Note that Categories should be set appropriately for the application type (in this example, a multimedia app).
* Now update the mime database with:
$ update-mime-database ~/.local/share/mime
Programs that use mime types, such as file managers, should now open '*.foo' files with foobar.  (You may need to restart your file manager to see the change.)
