But its a large application (lots of forms) that is updated everyday by
download (liveupdate-function) to hundreds of clients, its 18 meg
uncompressed, with zip or other compression its around 3MB
Saves alot of time if you count in all clients.
I am not sure if decompressing a ZIP or CAB archive on the client within the
updating process is sufficient:
ZIP files:
The Zip, GZip, BZip2 and Tar Implementation For .NET

The VB.NET Resource Kit contains zipping functionality too (note that the
Resource Kit is not available any more, so the answer applies for the case
that you already have a copy of the Resource Kit):
The Visual Basic .NET Resource Kit
<URL:http://msdn.microsoft.com/vbasic/vbrkit/>
It contains ComponentOne Zip for .NET:
ComponentOne ZipT for .NET
<URL:http://www.componentone.com/products.aspx?TabTypeID=1&ItemType=1&PanelIndex=14 &ItemID=53569&SubCategoryTypeID=0&TabMapID=57&TabI D=70>
Using J#'s zip functionality:
Using the Zip Classes in the J# Class Libraries to Compress Files and Data
with C#
<URL:http://msdn.microsoft.com/msdnmag/issues/03/06/zipcompression/>
..NET 2.0 will contain ZIP support too.
CAB files:
Microsoft Cabinet Software Development Kit
<URL:http://support.microsoft.com/?scid=kb;EN-US;310618>
You can build CAB files using the "MAKECAB.EXE" utility that is IIRC
included in Windows. For extracting CAB files, you can use Microsoft's
"EXTRACT.EXE", which is available on the Windows XP CD or as part of the
Windows XP Support Tools:

Alternative you can use p/invoke on 'SetupIterateCabinet'. A VB6 sample can
be found here:
