Compressed versus Actual File

The most important thing to keep in mind when using ZipStream is to 
remember that the files on the ZipStream path are actually files on a 
standard OS/2 File System drive.  There is not actually two copies of the 
file, only the one.  You should therefore not think that as you can now 
access the files from the ZipStream path, they can be deleted on the 
standard OS/2 path.
