Drag and Drop Operation

For Drag and Drop, just drag a folder or file object from one of the 
Drives Disk objects to the ZipStream Compress object  and the contents of 
that folder or object will be compressed. 

Note:  By default, this operation will not compress sub-directories.  If 
you wish to compress sub-directories via this method, you will need to add 
an '/S' switch to the objects parameters settings.  Refer to OS/2 help on 
how to adjust object settings.
