Loop Through Folder AND Sub-Folders and Print All Files

How to a create a Macro that will search through a folder, and all subfolders, and print all files?  The files I am opening are linked and must be updated when opened/printed.  I don't want to have to click "Yes" to the update each time (to a few hundred files).  I tried a few programs from google search but they don't search subfolders and they didn't resolve the requirement to update the file.  Thank you.

Here is the answer to the second part of your question - to disable "update" prompt while opening excel file..

So there are known sub-directory in folders ? or you have to get the name of sub-folder as well ?

I think we can come up with some kind of macro to pick up file and print it

Please provide more details.....if possible attach sample...

Unknown sub folder names. That'd be great if you could.

You will need to set up the QueryRefresh registry entry in the link hitsdoshi1. Then you should be able to run this VBA code without interruption.
Option Explicit

Sub PrintAll()
    FindFiles "M:\Allwork", "*.xl*" '<--- edit for your root folder.
End Sub

Sub FindFiles(strFolder As String, strFilePattern As String)
    Dim strFileName As String
    Dim strFolders() As String
    Dim iFolderCount As Integer
    Dim i As Integer
    Dim xlWbk As Workbook
    
    'collect child folders
    strFileName = Dir$(strFolder & "\", vbDirectory)
    Do Until strFileName = ""
        If (GetAttr(strFolder & "\" & strFileName) And vbDirectory) = vbDirectory Then
            If Left$(strFileName, 1) <> "." Then
                ReDim Preserve strFolders(iFolderCount)
                strFolders(iFolderCount) = strFolder & "\" & strFileName
                iFolderCount = iFolderCount + 1
            End If
        End If
        strFileName = Dir$()
    Loop
   
    'process files in current folder
    strFileName = Dir$(strFolder & "\" & strFilePattern)
    Do Until strFileName = ""
        DoEvents
        Set xlWbk = Workbooks.Open(strFolder & "\" & strFileName)
        xlWbk.PrintOut
        xlWbk.Close
        strFileName = Dir$()
    Loop
   
    'look through child folders
    For i = 0 To iFolderCount - 1
        FindFiles strFolders(i), strFilePattern
    Next i
End Sub

Thank you Graham.  I don't know what this means,

"You will need to set up the QueryRefresh registry entry in the link hitsdoshi1. Then you should be able to run this VBA code without interruption."

Can you please explain?  Thanks.

Ok, that was stupid.  Nevermind.  I just woke up, a little groggy.  Ok, this looks great.  One problem, its going to be next to impossible to access/change regedit at work due to the security settings.  I will file a request with IT and hopefully it can be done.  I will try this on Monday.  Thank you very much Graham!

Sorry, there was a typo that left the sentence a bit garbled.

Hmmm, weird.  I was able to add the DWORD.  I'm going to try it.  Anyway to adjust the above so that it only prints from page 1 to page 1?

Ok, so after adding to regedit I restarted my pc and then ran the Sub().  Unfortunately, its still asking me to "update" or "don't update".  Any suggestions?

Sorry for the real time posts.  I finally got the update prompt to go away by selecting Tools -> Options -> Edit -> (Uncheck) Ask to Update Automatic Links.  But now after it prints the file it ask me if I want to save it before closing it.  How can I elect "Yes" automatically?  Thanks.

Ok so that was stupid.  I added "xlWbk.Save" after "xlWbk.PrintOut".  So I think that settles it.  This is now resolved.  Thank you very much Graham.
