Replace text in word file in all sub folders - vba

Question

I am putting together a VBA macro that:
1.reads a folder
2.creates a collection of all its subfolders
3.loops through all the subfolders and find any word document ending in .doc
4.in each .doc file: replace a bit of text and save then close the documents.
This macro doesn't work correctly: it doesn't replace the text in any word documents in the subfolders.
It doesn't actual open any word document, I am unsure wether it should open each word doc one after another or if it runs in the background.

Dim file
Dim path As String
Dim strFolder As String
Dim strSubFolder As String
Dim strFile As String
Dim colSubFolders As New Collection
Dim varItem As Variant
' Parent folder including trailing backslash
'YOU MUST EDIT THIS.
strFolder = "G:\2009\09771\Design\ESD\Commercial Tower KSD1\Green Star As Built\Round 1 Submission - Draft\02. Indoor Environment Quality"
' Loop through the subfolders and fill Collection object
strSubFolder = Dir(strFolder & "*", vbDirectory)
Do While Not strSubFolder = ""
Select Case strSubFolder
Case ".", ".."
' Current folder or parent folder - ignore
Case Else
' Add to collection
colSubFolders.Add Item:=strSubFolder, Key:=strSubFolder
End Select
' On to the next one
strSubFolder = Dir
Loop
' Loop through the collection
For Each varItem In colSubFolders
' Loop through word docs in subfolder
'YOU MUST EDIT THIS if you want to change the files extension
strFile = Dir(strFolder & varItem & "*.doc")
Do While strFile <> ""
Set file = Documents.Open(FileName:=strFolder & _
varItem & "\" & strFile)
' Start of macro 1replace text GS-XXXAB with GS-1624AB

Your code worked for me with below changes
From
strFile = Dir(strFolder & varItem & "*.doc")
To
strFile = Dir(strFolder & varItem & "\" & "*.doc")
Make sure the path for folder is correct in strFolder Variable. Eg( strFolder = "C:\Users\Santosh\Desktop\tes\")
