Is there a way to do this without using a 3rd party application?

Thanks

Here is a way to zip using a Process:

    Private Sub srZip_CSV_File()
        'Zip RetailCustLineData.csv to RetailCustLineData.zip and pause until completed before continuing
        Dim P As New Process
        P.StartInfo.FileName = "C:\Program Files\WinZip\WINZIP32.EXE"
        P.StartInfo.Arguments = "-min -a C:\FTP-Data\Icentrix\RetailCustLineData.zip C:\FTP-Data\Icentrix\RetailCustLineData.csv"
        P.Start()
        P.WaitForExit()
        ' ...continue with other stuff...
    End Sub

Be sure to change this line to zip a folder:  (example)

P.StartInfo.Arguments = "-min -a C:\FTP-Data\Icentrix\<folder_name.zip> C:\FTP-Data\Icentrix\*.*"

Change it to your names.
There aren't any built-in .NET classes that handle ZIP compression. Also, the "built-in" zip compression for windows (Right click -> send to -> Compressed Folder) does not have a command line interface unless you've downloaded the MS support tool kit.

So, you will either need to download a 3rd party .NET zip library (such as http://www.icsharpcode.net/opensource/sharpziplib/ - if you download the compiled assembly, it will work with a VB.NET application) or make a call to a 3rd party zip utility with a command line interface  (or Microsoft's COMPRESS utility, if you do have the support tools installed) using "Process.Start(executableFile, args)".

Gzip is better, the example posted shows you how to pack a file, not pack and compress. Still thank you for your help
