Macro for all docx in subdirectories

[createur]

Hi. I'm not the best with macros and VBA but I have a macro that I use to style documents that I want to apply to all files spread throughout a series of subdirectories. I've been trying a few things that I've seen suggested here and there but I haven't figured out anything that works. The macro I want to apply is as follows:

Sub QuickFormat()
'
' QuickFormat Macro
' Quick Format for Books
'
Selection.WholeStory
With Selection.ParagraphFormat
.SpaceBefore = 0
.SpaceBeforeAuto = False
.SpaceAfter = 0
.SpaceAfterAuto = False
.LineSpacingRule = wdLineSpaceSingle
.LineUnitBefore = 0
.LineUnitAfter = 0
End With
Selection.Find.Execute Replace:=wdReplaceAll
ActiveWindow.ActivePane.LargeScroll Down:=3
Selection.Find.ClearFormatting
Selection.Find.Replacement.ClearFormatting
With Selection.Find
.Text = "^l"
.Replacement.Text = "^p"
.Forward = True
.Wrap = wdFindContinue


.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
End With
Selection.Find.Execute Replace:=wdReplaceAll
ActiveWindow.ActivePane.LargeScroll Down:=3
Selection.Find.ClearFormatting
Selection.Find.Replacement.ClearFormatting
With Selection.Find
.Text = "^p"
.Replacement.Text = "^p^p"
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
End With
Selection.Find.Execute Replace:=wdReplaceAll
ActiveWindow.ActivePane.LargeScroll Down:=3
Selection.Find.ClearFormatting
Selection.Find.Replacement.ClearFormatting
With Selection.Find
.Text = "^p "
.Replacement.Text = "^p"
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
End With
Selection.Find.Execute Replace:=wdReplaceAll
ActiveWindow.ActivePane.LargeScroll Down:=3
Selection.Find.ClearFormatting
Selection.Find.Replacement.ClearFormatting
With Selection.Find
.Text = "^p "
.Replacement.Text = "^p"
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
End With
Selection.Find.Execute Replace:=wdReplaceAll
Selection.WholeStory
With Selection.ParagraphFormat
.SpaceBefore = 0
.SpaceBeforeAuto = False
.SpaceAfter = 0
.SpaceAfterAuto = False
.LineSpacingRule = wdLineSpaceSingle
.CharacterUnitFirstLineIndent = 0
.LineUnitBefore = 0
.LineUnitAfter = 0
End With
Selection.MoveLeft Unit:=wdCharacter, Count:=1
Selection.WholeStory
Selection.LanguageID = wdEnglishAUS
Application.CheckLanguage = False
Selection.Find.ClearFormatting
Selection.Find.Replacement.ClearFormatting
With Selection.Find
.Text = "^p^p^p^p"
.Replacement.Text = "^p^p"
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
End With
Selection.Find.Execute Replace:=wdReplaceAll

End Sub

Any help would be greatly appreciated.
