FlashUploadDeniedExtensions

This option specifies the flash upload extensions which you don't wish to use in FCKeditor. Example: 

FCKConfig.FlashUploadDeniedExtensions = ".(swf)$" ;

If you leave this option empty none extension will be denied.

NOTE: if you leave allowedExtensions empty and you will put something in deniedExtensions 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 allowedExtensions and put the unwanted ones in the deniedExtensions. Only in this way you will secure your server from junk.
