<p><span style='font-size:12.0pt'>Filters are patterns used to select directories and files.</span>
<p>
<b><span style='font-size:12.0pt'>Filters fall into four categories:</span></b>
<ol>
<li> <i>Directory</i> names
<li> File <i>extensions</i>, matches files
<li> <i>Wildcard</i>, matches directories and files
<li> <i>Exclude</i> files or directories
</ol>
1. <b>Directory</b> filters must end in a back slash.
Example:�� <b><span style='color:red'>debug\</span></b><span style='color:red'></span>
<br>
Directory filters only match on directory names and cause
the directory and all of its subdirectories to be selected.
<p>
2 File <b>extension</b> must start with a decimal point.
Example:�� <b><span style='color:red'>.obj</span></b>
<br>File extension filter only matches on files.
<p>3. <b>Wildcard</b> is a collection of characters with one
or more wildcard characters *.
<br>Wildcard can appear multiple times. <b>*</b> matches zero or more characters.
<blockquote>
Example: <b>Connect*.xml </b>
<br>Example: <b>*foo*bar.* </b>
</blockquote>
<p>The wildcard filter is tested against the fulll file or
directory path so it is common for all wildcard patterns to start with <b>*</b> to match on any
prefix of disk drive letters and subdirectories.
<p>
<blockquote>
Examples:
<br>
<table border=1>
<tr style="background-color:#c0c0c0;"><td> Pattern <td>Test Against <td>Results
<tr><td> foo* <td>foobarcar <td>match
<tr><td> foo* <td>carbarfoo <td>no match
<tr><td> *foo <td>carbarfoo <td>match
<tr><td> *foo\bin\* <td>foo\junk <td>no match
<tr><td> *foo\bin\* <td>foo\bin\ <td>match
<tr><td> *foo\bin\* <td>foo\bin\car.exe <td>match
<tr><td> *\bin\*.obj <td>c:\foo\bar\bin\car.obj <td>match
<tr><td> *\bin\*.o* <td>c:\foo\bar\bin\car.old <td>match
<tr><td> *\bin\*.o* <td>d:\bin\junk.obj <td>match
</table>
</blockquote>
<p>A filter can contain one or more filters separated by semicolons.
<blockquote>
Example: <b>Connect*.xml;.obj;obj\</b>
</blockquote>
<p>4. The <b>exclude</b> filter is evaluated last and only for matches in the current filter. Exclude filter starts with a <span style='color:red'>minus</span> sign.
<blockquote>
Example: <b>*\bin\*;</b><b><span style='font-size:12.0pt;color:red'>-</span>*.exe</b>
</blockquote>
<p>The above example will match on the directory "<b>bin</b>" and all of its subdirectories and files.
The exclude pattern will exclude all files with extension ".<b><span style='color:red'>exe</span></b>" from the matched files.
NOTE: the exclude only works on <b>File</b> and <b>Wildcard</b> filters and not simple <span style='color:red'>Directory</span> name filters.
<p>
The following will <b><span style='color:red'>not</span></b> work because the members of bin directory are not tested individually.
<blockquote>
Example: <b>bin\;-*.exe</b>
</blockquote>
<p><b><span style='font-size:12.0pt'>Special Global Exclude Filter:</span></b>
<p>If one or more exclude filters have their Filter name set
to <b><span style='color:#E36C0A'>'never'</span></b>, they are always evaluated
to prevent files from being located.
<p>
<blockquote>
Example:<br>
<table border=1>
<tr style="background-color:#c0c0c0;"><td>Filter <td>Details <td>Description
<tr><td><b><span style='color:#E36C0A'>never-exe</span></b><td> -*.exe <td>Don't remove executables
<tr><td><b><span style='color:#E36C0A'>never-cpp</span></b><td> -*.cpp <td>Don't remove soource files cpp
<tr><td><b><span style='color:#E36C0A'>never-zed</span></b><td> -*\Zed*\* <td>Don't remove Zed graph directories
</table>
</blockquote>
<p>Use <b>Add</b> and <b>Delete</b> buttons to manage your collection of filter rules.
<br><b>Double click</b> on a row to change its value.
<br><b>Right click</b> if you want to Export the filter rules as CSV
<br><Font color=red>Filter names must be unique. Duplicate filters will be ignored next time you restart.</font>
<p><b><span style='font-size:12.0pt'>Bookmarks:</span></b>
<blockquote>
<p>Use the bookmarks to memorize a set of filter rule checkmark states and Path setting.
<br>Use the bookmark <b>Add</b> button to add a new bookmark to remember the current settings.
<br><b>Double Click</b> on a bookmark to activate its settings.
<br>Press the <b>'Set'</b> button to refresh the current state of a bookmark to the current list of active filter rules and Path.
</blockquote>
<p><b><span style='font-size:12.0pt'>Search Path</span></b>
<blockquote>
Keep folder search path <b>empty</b> when you set a bookmark if you want its application to be applied to an existing path.
