		<summary type="html">&lt;p&gt;Created page with &amp;quot;﻿&lt;a href=&quot;/Category:Settings:Editor&quot; title=&quot;Category:Settings:Editor&quot;&gt;Category:Settings:Editor&lt;/a&gt;The &amp;#039;&amp;#039;&amp;#039;Editor » Hex mode&amp;#039;&amp;#039;&amp;#039; branch of &lt;a href=&quot;/Category:Settings&quot; title=&quot;Category:Settings&quot;&gt;Settings&lt;/a&gt; has the following options.  &amp;lt;h2 class=&amp;quot;setting&amp;quot;&amp;gt;Open files containin...&amp;quot;&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;﻿[[Category:Settings:Editor]]The &amp;#039;&amp;#039;&amp;#039;Editor &amp;amp;raquo; Hex mode&amp;#039;&amp;#039;&amp;#039; branch of [[:Category:Settings|Settings]] has the following options.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;h2 class=&amp;quot;setting&amp;quot;&amp;gt;Open files containing hex 00&amp;#039;s (nulls) in hex mode&amp;lt;/h2&amp;gt;&lt;br /&gt;
When a file is loaded the editor checks the first 7 kilobytes of the file, and if it contains more than two nulls (00 byte) the file is assumed to be a binary (instead of plain text) file. If this option is selected, any file containing nulls (other than files with UTF-16 encoding, where hex nulls are expected) will be opened automatically in hex mode.  If this option is unchecked, then a file containing hex nulls would be opened as a normal text file for editing.  &lt;br /&gt;
&lt;br /&gt;
The editor will respect and retain the active mode (text mode or hex mode) for the active file when reloading the file (either via &amp;quot;Revert to Saved&amp;quot;, file change detection, or file change polling).&lt;br /&gt;
 &lt;br /&gt;
&amp;lt;h2 class=&amp;quot;setting&amp;quot;&amp;gt;Allow editing of text files with hex 00&amp;#039;s without converting them to spaces&amp;lt;/h2&amp;gt;&lt;br /&gt;
Since nulls are not valid in plain text files, they will be converted to spaces if you edit a file containing hex nulls in text mode (again, with the exception of UTF-16 files). This conversion happens &amp;#039;&amp;#039;only&amp;#039;&amp;#039; if you edit the file. Select this option to prevent the conversion of hex nulls in this case.&lt;br /&gt;
&lt;br /&gt;
We do not recommend editing binary files in plain text mode, as this may cause unwanted conversion of binary data if you&amp;#039;ve forced the editor to treat it as plain text. &lt;br /&gt;
&lt;br /&gt;
Additionally, enabling this setting may cause some functionality (like the clipboard) not to work past hex nulls, although this should not effect general editing.&lt;br /&gt;
 &lt;br /&gt;
&amp;lt;h2 class=&amp;quot;setting&amp;quot;&amp;gt;Number of hex characters per line&amp;lt;/h2&amp;gt;&lt;br /&gt;
This setting defines the number of hex characters to be shown in each line of the [[Hex edit|hex editor]] display.  The application must be restarted before any changes to this value take effect.&lt;br /&gt;
&lt;br /&gt;
