Script to extract files from folders

I need a turnkey Windows script that will scan a bunch of folders and subfolders and extract windows media audio files *.wma and place them all into a single folder.  I am not sure how best to handle files with duplicate filenames, but I am pretty sure there are none.  Maybe the duplicates could get placed a folder named duplicate.

Will there need to be a list of base folders to scan into, or are you wanting to scan a single folder and all it's subfolders?

I have a single folder called 'Music' but inside of that I have 35 folders and then those 35 folders have various subfolder structures.  Some have a single subfolder, but others might have a folder within their subfolders.  So I have varying levels of subfolders.  I think the script will need to check for unlimited depths of folder levels.

So I can provide the path to the root folder for it to start its scanning of everything within that root folder.

Okay, here's a script for this job, adjust the paths as needed.

' File I/O constants
Const ForReading = 1, ForWriting = 2, ForAppending = 8

' Source and xdestination folder names, and extension of files to move
strBaseDir = "C:\EE\EE28166353\Files"
strDestDir = "C:\EE\EE28166353\Merge"
strBaseExt = ".wma"

' Log file for duplicate errors
strLogName = "C:\EE\EE28166353\logfile.txt"

' Create filesystem object
Set objFSO = CreateObject("Scripting.FileSystemObject")

' Open log file
Set objLog = objFSO.OpenTextFile(strLogName, ForWriting, True)

' Call recursive subroutine to move all files in a folder, and all child folders
MoveFiles objFSO.GetFolder(strBaseDir)

' Close log file, release objects
Set objLog = Nothing
Set objFSO = Nothing

Function MoveFiles(objFolder)
    ' Process all files in this folder
    For Each objFile in objFolder.Files
        ' Is it the extension we want to move
        If LCase(Right(objFile.Name, Len(strBaseExt))) = LCase(strBaseExt) Then
            ' Build new destination path
            strDestPath = strDestDir & "\" & objFile.Name
            ' Only move it the destination file doesn't exist, otherwise log and leave alone
            If objFSO.FileExists(strDestPath) Then
                objLog.WriteLine "Duplicate file:[" & objFile.Path & "], [" & strDestPath & "]"
                objFSO.MoveFile objFile.Path, strDestPath
            End If
        End If

    ' Process all subfolders in this folder
    For Each objSubFolder in objFolder.Subfolders
        MoveFiles objSubFolder
End Function
