QSearchFolders creates search folders and manage existing search
folders in all versions of MS Outlook and in each place in an
Outlook tree. It makes the automatic scanning of Outlook folder such
as email and contacts, tasks, calendars possible.

One of the new features of Outlook 2003 are search folders, once
created the for example show all your unread messages in all folders
or messages matching any criteria. Search folders automatically
search the specified folders in the background and update themselves
if the data changes.

Search folders are a part of MAPI, the data base engine on which
Outlook is based and are part of the definition since the first
version of MAPI which was introduced about 1995. In other words, all
versions of Outlook are able to display search folders, missing is
only a user interface which allows creating them. In fact, all
versions of Outlook are using search folders in the extended search
dialog.

The extended search creates a search folder in the non-visible part
of the Outlook tree and opens a window displaying this folder. In
some cases, the search folder will not be deleted and keeps up
searching for ever, slowing down Outlook.

QSearchFolders allows deletion of non-visible search folders.
