Sometimes it is necessary for a target container to know the name of the source container. This name could carry some location information. For example, the default operation when dragging objects between containers is a Move. However, in the case of file folders on different drives, this default would be changed to a Copy operation. Thus, a file folder would fill this field with the drive and path information for a file, for example, A:\SUBDIR1\SUBDIR2\. A database container, on the other hand, might fill this field with the fully qualified OS/2 file name of the database.
