Tools - Settings - Programs -
Under "Tools → Settings → Programs" in the tab "Viewers", the user may define programs for showing files, depending on their file extension.
Assignment of filters and programs (viewers)
Different file extensions (in the column "filter") may be assigned to different viewers (in the column "programs").
In the above example, the viewer "Viewer.exe" is assigned to files with the extensions "mp3" and "avi".
Calling the viewers
On activation of the menu item "File → View" or the hotkey "F3", the listed filters are analyzed sequentially from the top down. The highlighted file is opened by the viewer assigned to the first matching filter. Only checked rows are taken into account when matching a filter.
If no filter matches the highlighted file, it will be shown by the FreeCommander viewer as configured in the menu item "Tools → Settings → View → Viewer".
The following buttons are available for editing the list of filters and viewer programs:
The input box "program" specifies the program which should perform the action for the highlighted row.
The input box "parameter" specifies any parameters required for the program in the highlighted row.
