You can configure an application to view any type of file using this window. Some links to suitable viewers can be found in the document <a href="../sources.html#viewers"><cite>Sources of Fetchers and Viewers</cite></a>
<P>
This window is split into three main areas.
<BR>
<HR><img src="images/ext-list.gif" align=left>A scrolling list showing the configured Extension/FileTypes. One of which may be hilighted. Hilighting an entry, by clicking on it, allows the Action for that filetype to be changed. The list can be scrolled quickly by clicking on an arrow while holding the <kbd>Shift</kbd> key.
<br clear=all><HR><img src="images/ext-new.gif" align=left>A writable field and button to allow new types to be added. The writable field should contain the RISC OS filetype (if there is one assigned) starting with an ampersand (&) and no leading zeros. You should also put the extensions that any files of this type may have. These are usually between two and four letters and each type may have more than one possible extension. Each Filetype or Extension should be separated by a single comma.
<br clear=all><HR><img src="images/ext-act.gif" align=left>An action area where what is done with the currently hilighted type is is shown (This will be shaded when there is no hilighted entry in the scrollable area.
<p>This actually consists of two parts, a list of the file extensions (Which you can alter) and types and the Action that is performed on a matching file.
<br clear=all>
The following Actions are available
<dl>
<dt>Ignored
<dd>If selected then the file is ignored!
<dt>Filer_Run
<dd>This option allows you to run the file as if you double clicked on it. It is only useful if the <a href="../scantype.html">ScanType</a> file has given the file a RISC OS filetype and the application that uses this kind of file has been <quote>seen</quote> by RISC OS.
<DT>Load Into Webster
<dd>Allows you to get webster to show the file. Webster currently only handles files of the following types.
<ul>
<LI>GIF (RISC OS type &695) - an image file.
<LI>XBM (No RISC OS type, although they do contain only text) - an image file.
<LI>JPEG (&C85, or JPG) - another image type.
<LI>Sprites (&FF9) - The RISC OS standard image type.
<LI>Text (&FFF, TXT or TEXT) - pure text.
</ol>
<dt>Open Save Box
<DD>Allows you to save the file for later use.
<DT>Command
<DD>The most complex option. Allowing you to pass the file as a parameter to any command. (<A href="#command">Detailed below</a>)
<dt>ArcWeb Render
<DD>When selected a standard Wimp Message to sent that can be caught by any running application. (Currently only useful for sounds files, e.g. those with the extension au or snd, which can be played using <a href="../sources.html#viewers">SoundCon</a>)
The command line options allows any RISC OS application (Wimp Based or not) to be used to <quote>view</quote> fetched files.
<P>
The command line Should be any command with %0 placed where you want the filename. You can drag a file of application to the field to partially setup the info for you, but you must put the %0 in your self. All the following can be valid commands.
This assumes <a href="../sources.html#viewers">Fplay</a> is in a directory pointed to by Run$Path, and both <a href="../sources.html#viewers">!MPEG</a> and !ARPlayer have been seen by RISC OS.
<HR>
<h2>Quick Referance</h2>
<ol>
<LI>Where possible the <a href="../scantype.html">ScanTypes</a> file is used to assign a RISC OS filetype to the fetched file. This make handling the file much more flexable.
<LI>For changes to take effect, and the required files to be created, you must either select another choices option or Click on the <quote>Save</quote> button.
<LI>You should put possible extensions and any RISC OS filetype (Starting with &, no leading zeros) in the Extension/Filetype list for each Entry.
<LI>Entrys in the Extension/FileType list must be in capitals and separated by commas.
<LI>You need to click on an entry in the list before you can change any entry.
<li>Clicking on a Scroll Arrow with Shift held Scrolls three entries at a time.
<LI>You can only create new entrys via the New button and the field to it's left.
<LI>If no entry matches the Clicked URL a Save Box is opened.
<li>This window still needs some work on it's Format and how it is updated.
