There are a few ways to associate file-types to programs in Puppy. The following descriptions are based on the RoxFiler ROX Filer and may not work with other file managers.

Sometimes you won't be able to associate a file to a program because its MIME-type has not been defined. Looking in the file's Properties > Type will reveal only a general type (guessed by its content) - for example text/plain or application/x-executable. In this case you need to HowToAddMIMEType add a mime type.

Default Action loads the file into the appropriate program when it is clicked (left-clicked) depending on its InternetMediaTypes MIME-type. ROX will look for file named after the MIME type, firstly in-

For example, if the MIME-Type is application/x-audacity-project

then ROXFiler ROX will look for a file called application_x-audacity-project (notice the / is replaced by an _).

Typically, the file is a script file or a link to an executable. Often, it is a link to a program's AppsDesktop .Desktop stored in /usr/share/applications.

ROX provides a graphical way to set Default-Action:

Right-click association loads the file into a program chosen from the 'right-click File menu' - Right-clicks menu > File 'document.doc' > Doc program

The options in the menu depend on its InternetMediaTypes MIME-type. ROX will list any file in the directory named after the MIME-type in ~/.config/rox.sourceforge.net/MIME-types/[MIME-type directory]

For example, if the MIME-Type is audio/mpeg

then ROXFiler ROX will list the file in the directory called .audio_mpeg (notice the . at the start and the / is replaced by an _).

Typically, the files are script files or links to an executables. Often, they are links to a program's AppsDesktop .Desktop stored in /usr/share/applications.

ROX provides a graphical way to set Right-click Association:

Open-with Association loads the program when the user goes - Right-clicks menu > File 'document.doc' > Open With > Program

Open-with Association allows a program to open any file. It is accessed by the 'right-click File menu' - Right-clicks menu > File 'document.doc' > Open With

The options in the menu depend on the files (not the folders) in the directory ~/.config/rox.sourceforge.net/MIME-types/

Typically, the files are script files or links to an executables. Often, they are links to a program's AppsDesktop .Desktop stored in /usr/share/applications.

ROX provides a graphical way to set Open-With Association:

ROXApplicationDirectory ROX Application Directory - special ROX desktop environment directory
