With this setting you can tell XFolder not to subclass any folders.

Important note: Many of XFolder's features RELY on folder subclassing. Enabling this setting will severely limit XFolder's capabilities. This setting is only meant to be a "last resort" in case XFolder does not work properly on your system.

Enabling this setting will automatically disable the following XFolder features:

- Folder hotkeys;
- Auto-scroll Tree views;
- the "Folder content" functions;
- folder status bars;
- folder and menu system sounds.

Only folders which are opened after changing this setting will be affected. Especially the Desktop will not be affected. If you experience severe problems with XFolder, you will have to reboot or restart the WPS.

Detailed explanation:

As you might know, in OS/2 (and Windows too), windows communicate with "messages" to notify each other of certain events. The base operating system also uses messages to notify windows of certain events. For example, every time you move or click the mouse or press a key, a window receives a respective message so it can react to it.

Now, "subclassing" is a very powerful feature of OS/2. It allows a program to intercept messages for a certain window or window class and thus make window react differently. XFolder uses this feature for example to intercept keyboard messages for folders; this is the way the folder hotkeys work.

Subclassing might lead to problems, however, if several programs try to subclass a window and do not know of each other. For example, the WPS uses subclassing intensively itself (which is not very well documented), and WPS enhancers other than XFolder (e.g. Object Desktop) implement some of their features this way too. XFolder has no way of detecting what these programs do, so if you feel that something is going wrong, you can tell XFolder to leave folder windows alone.
