Example:<br /> &lt;pre&gt;FCKConfig.LinkUploadDeniedExtensions = &quot;.(7z|rar|zip)$&quot;&amp;nbsp;;<br /> &lt;/pre&gt; <br /> If you leave this option empty none extension will be denied.<br /> <br /> '''NOTE''': if you leave [[FCKeditor 2.x/Developers Guide/Configuration/Configuration Options/LinkUploadAllowedExtensions|LinkUploadAllowedExtensions]] empty and you will put something in LinkUploadDeniedExtensions e.g.pdf it will allow the upload of all the files exept the pdf. However it isn't a good way to secure your server from unwanted uploads. The best way is to put all of the prefered extensions in [[FCKeditor 2.x/Developers Guide/Configuration/Configuration Options/LinkUploadAllowedExtensions|LinkUploadAllowedExtensions]] and put the unwanted ones in the LinkUploadDeniedExtensions. Only in this way you will secure your server from junk.</div>
