Zip file to a zipped folder

I'm wondering how I can move a file to an already zipped file folder.

Example:

Move myfile.txt to zippedfile.zip\new folder\items\

I tried using the command line in 7 zip but couldn't find the right paramentors. If this can be done through VB or command line, Ill take either way.

Thanks.

I tried the code posted here, then modified the Sub Zip_Activity so it only creates a zip file if the zip file doesn't already exists, otherwise the code created the zip file and the original contents of the zip file were lost.

Sub Zip_Activity.....

Code:

---

    Select Case UCase$(Action)       
        Case "ZIPFILE"           
            If Right$(UCase$(sFileDest), 4) <> ".ZIP" Then
                sFileDest = sFileDest & ".ZIP"
            End If
       
            ' Only create zip if zip not found!
            If bFileExists(sFileDest) = False Then
                If Not Create_Empty_Zip(sFileDest) Then
                    GoTo EH
                End If
            End If

            Set ShellClass = New Shell32.Shell
            Set Filedest = ShellClass.NameSpace(sFileDest)           
            Call Filedest.CopyHere(sFileSource, 20)

---

' Check for file exist sub...

Code:

---

Private Function bFileExists(sFile As String) As Boolean
    On Error Resume Next
    bFileExists = ((GetAttr(sFile) And vbDirectory) = 0)
End Function

---

Once the source file is added to your zip you can just use the Kill command to delete the source file.

I tried using the move command Call Filedest.MoveHere(sFileSource, 20) but the source file didn't get deleted, but did get added to the zip file.
