I need to unzip all files in a folder using SSIS. Right now I am able to unzip individual files by hardcoding their names. I want all to be done at once.

You could call a program like 7-zip (7za.exe needs no installation) from the a script control in SSIS.

When I am trying to use a execute process task and providing the winzip32.exe in executables. I am facing problems in sending all zip file names as argument to that. Please let me know how to send the file names as an argument in execute process task.

Commented:
If you use 7-zip you can execute it in a shell from a VB.NET script control

Thanks. Can you please send me 1 example on how to use 7-zip and execute it in a shell from a VB.NET script control.

I;ve edited some old vbScript I have but a function to zip a file should look something like this:

Private Sub ZipFile(ByVal sFromPath As String, ByVal sToPath As String, ByVal sFromFileName As String, ByVal sToFileName As String)

        Dim s7za As String = "C:\Program Files\7-Zip\7za.exe"
        Dim sArguments As String
        Dim myProcess As New System.Diagnostics.Process

        Dim sFullFromFileName As String
        Dim sFullZipFileName As String

        sFullFromFileName = sFromPath & sFromFileName
        sFullZipFileName = sToPath & sToFileName

        sArguments = " a -tzip -mx1 -y  """ & sFullZipFileName & """ """ & sFullFromFileName & """"
        myProcess.Start(s7za, sArguments)

    End Sub

This script is agin to zip a single file. I am in need of unzipping all files in a folder.

Commented:
You could call it once for each file in the folder and it will add each file to the zip

How can I do that using the "Execute Process Task" in SSIS. Can you please explain me that?

Commented:
You can do it from a script control. You can just write .NET code in a scriipt control so can erxecute things using System.Diagnostics.Process.
