Hello, Check this link. Thanks

This prog from this link i use, but i can't remove the DivX file type, can't this be done with regedit ?

You might look around here HKEY_CLASSES_ROOT and here HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts http://extension.nirsoft.net/divx Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]
