Loop Through All Subfolders Using VBA

Question

I m looking for a VBA script that will loop through all subfolders of a specified folder  When I say all subfolders  I mean each folder inside the specified folder  and each folder inside of that  and each folder inside of that   in theory there could be infinite nested subfolders  but in actuality it will probably not go above 3 or 4  I m using the VBA Scripting Runtime objects  so that once I loop into the folder I can check properties of some files  but I know how to do that part    Thank you for your help   This question is different from the listed  similar  questions in the previous questions contained known directories  whereas the need here was to find known and unknown directories  Also needed multiple layers of subdirectories  You guys really should just read the question before you fire off  duplicate

And to complement Rich s recursive answer  a non-recursive method   Public Sub NonRecursiveMethod       Dim fso  oFolder  oSubfolder  oFile  queue As Collection      Set fso   CreateObject  Scripting FileSystemObject       Set queue   New Collection     queue Add fso GetFolder  your folder path variable    obviously replace      Do While queue Count  gt  0         Set oFolder   queue 1          queue Remove 1  dequeue             insert any folder processing code here            For Each oSubfolder In oFolder SubFolders             queue Add oSubfolder  enqueue         Next oSubfolder         For Each oFile In oFolder Files                 insert any file processing code here            Next oFile     Loop  End Sub   You can use a queue for FIFO behaviour  shown above   or you can use a stack for LIFO behaviour which would process in the same order as a recursive approach  replace Set oFolder   queue 1  with Set oFolder   queue queue Count  and replace queue Remove 1  with queue Remove queue Count   and probably rename the variable

Just a simple folder drill down    sub sample       Dim FileSystem As Object     Dim HostFolder As String      HostFolder    C         Set FileSystem   CreateObject  Scripting FileSystemObject       DoFolder FileSystem GetFolder HostFolder  end  sub  Sub DoFolder Folder      Dim SubFolder     For Each SubFolder In Folder SubFolders         DoFolder SubFolder     Next     Dim File     For Each File In Folder Files           Operate on each file     Next End Sub
