An OleFile enables you to transparently persist embedded or linked OLE objects into files. An OleFile works with an OleClient or OleControl widget to perform persistence operations on their contained OLE objects. Items stored into an OleFile are identified by a unique name that you provide when the object is saved.

Using instances of OleFile, you also can associate arbitrary data attributes with a stored OLE object. These attributes are referenced for storage and retrieval by using the same name the object was stored under. You can use this feature, for example, to store various attributes of the OleClient widget containing the OLE object, such as, its position, width, and height.

There is an additional facility in OleFile to store and retrieve a set of data attributes that may be global to all the OLE objects stored within the file.
