VBScript to loop through folder containing zipped files and unzip files to a different folder

Question

I am a noob with an S-curl and flowing cape. I have a friend who downloads zipped font files to her desktop. She then opens the files up, copies the fonts to the C:\fonts folder and installs the fonts. The script is intended to be used on XP. I mentioned that I would help her automate the process. So my methodology was to make a script that will scan her desktop for the zip files she downloads, move those files off of her desktop to a folder I call ZipFonts which will be located in her My Documents folder. When ZipFonts is created, two folders, ZipStaging and CompletedZips will be created inside of it. The plan is to move the zipped files to the ZipFonts folder. I then want to loop through ZipFonts and empty the contents of the zipped files into the ZipStaging folder and then the zipped files will be moved into the CompletedZips folder. I have been doing this script piece by piece to make sure it works successfully. I have successfully been able to create the folders and move the zipped files from the desktop into the ZipFonts folder. When I run the loop to open the zipped files, I get the error "Line 44 / Char 4 / Object Required: 'objShellApp.Namespace(...)' / Code: 800A01A8"

I'm sure I spelled everything correctly and I use Notepad++ to make sure everything is defined. I put my Set object references inside and outside of the loop to see if that made a difference but I get the same error. What am I missing? [Code is Below]

Answer 1

Modifying the code from @Rich ever so slightly and tracking values with MsgBox statements in each part of the code, I did some weird stuff and came up with the following code. Which loops through, and unzips each file and moves the files to the ZipStaging folder. This was the major hurdle.

Public objFSO, objShell, objshellApp
Public SourceFolder, file
Public UserPoint, UserDesktop, UserDocs, ZFFolder, ZSFolder, CZFolder

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("Wscript.Shell")

UserPoint = objShell.ExpandEnvironmentStrings("%USERPROFILE%")
UserDesktop = (UserPoint & "\Desktop")
UserDocs = (UserPoint & "\My Documents")
ZFFolder = (UserDocs & "\ZipFonts\")
ZSFolder = (ZFFolder & "ZipStaging\")
CZFolder = (ZFFolder & "CompletedZips\")

Sub DoesZipExist
   Set SourceFolder = objFSO.GetFolder(UserDesktop)
   FOR EACH file In SourceFolder.Files 'Loop through the user's Desktop folder for files ending with .zip
      If Right(LCase(file.Name),4) <> ".zip" Then    
         KeepLooking = TRUE
      Else
         KeepLooking = FALSE
         Exit FOR
         Exit Sub
      End If
   Next
   If KeepLooking = TRUE Then
      MsgBox("There are no compressed files (files ending with extension .zip) on your desktop.")
      MsgBox("Please click OK to end.")
      WScript.Quit   
   End If
End Sub

Sub InitialFolderCreation
   If objFSO.FolderExists(ZFFolder) = FALSE Then
      Set SourceFolder = objFSO.CreateFolder(ZFFolder)'Create folder %USERPROFILE%\My Documents\ZipFonts
      Set SourceFolder = Nothing
      Set SourceFolder = objFSO.CreateFolder(ZSFolder)'Create folder %USERPROFILE%\My Documents\ZipFonts\ZipStaging
      Set SourceFolder = objFSO.CreateFolder(CZFolder)'Create folder %USERPROFILE%\My Documents\ZipFonts\CompletedZips
      Set SourceFolder = NOTHING
   End If
End Sub

Sub MoveFromDesktop 'Move folders from Desktop To ZipFonts folder
   Set SourceFolder = objFSO.GetFolder(UserDesktop)
   FOR EACH file In SourceFolder.Files 'Loop through the user's Desktop folder for files ending with .zip
      If Right(LCase(file.Name),4) = ".zip" Then
     'move the file into the %USERPROFILE%\My Documents\ZipFonts folder
         objFSO.CopyFile file.Path, ZFFolder, TRUE
         objFSO.DeleteFile file.Path
         '**figure out how to report that each file is being moved or display some sort of progress bar
         '**figure out how to report that file relocation has been completed for a few seconds
     End If
   NEXT
End Sub

Function Unzip(strFileName,strFolderName)
   'Create Shell.Application so we can use the CopyHere method
    Set objshellApp = CreateObject("Shell.Application")
   'Use CopyHere to extract files
   objshellApp.NameSpace(strFolderName).CopyHere objshellApp.NameSpace(FileHolder).Items
   Set objfso = Nothing
   Set objshellApp = Nothing
End Function

DoesZipExist
InitialFolderCreation
MoveFromDesktop

Set SourceFolder = objFSO.GetFolder(ZFFolder)
FOR EACH file in Sourcefolder.files
   FileHolder = file
   Unzip FileHolder, ZSFolder
NEXT
MsgBox ("All compressed (.zip) files have been extracted. Ending script.")
Wscript.quit

I know I left out a lot of unused variables and I didn't declare some of them, but I did say I was SuperNoob! Now I need to implement the code that @Rich mentioned to cleanup the temporary files, then I should be good to go!
