I am storing application data as a byte array in my database.  In this case
the application is a Media Player file of the form c:\medialfiles\file1.wmv.  
I guess the question could also apply to application files of form .doc or
.xls, etc.  What I would like to know is that when I recover the byte array
from my server containing the serialized file contents, do I have to stream
back to a file on disk to enable the parent application to run it or can I
somehow avoid disk operation and activate the application form the file
contents in memory in the form of a memorystream or some other in memory
format.  Can I avoid having to stream my application file back to disk and
still have my parent application load it?

Thanks,
Fred Herring
