Soft returns macro - vba

Question

How do I modify the following Word macro to convert soft returns to hard returns and process all files in subfolders as well using "new file" as an event trigger?
Sub ConvertReturns()
'This Sub loops through docx files in a folder, opens each file, finds manual line breaks, replaces each with a paragraph return, saves changed file to a new folder, closes original file.
Dim oSourceFolder, oTargetFolder, oDocName As String
Dim oDoc As Document
Dim oRng As Range
'Set paths to folders for original and converted files on user's hard drive.
oSourceFolder = "C:\Users\Administrator\Desktop\Unprocessed\"
oTargetFolder = "C:\Users\Administrator\Desktop\Processed\"
'Get a handle on the first file in the source folder
oFile = Dir(oSourceFolder & "*.doc")
'Continue doing the following steps until there are no more unprocessed files in the source folder
Do While oFile <> ""
'Open the file
Set oDoc = Documents.Open(FileName:=oSourceFolder & oFile)
'Get the name of the document you just opened
oDocName = Left(oDoc.Name, Len(oDoc.Name) - 3)
'Find all manual line breaks and replace them with paragraph markers
Set oRng = ActiveDocument.Range
With oRng.Find
.Text = "^l"
.Replacement.Text = "^p"
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchCase = False
End With
oRng.Find.Execute Replace:=wdReplaceAll
'Save the changed document with the same name but appended with "_Converted" in your target folder
oDoc.SaveAs oTargetFolder & oDocName & "doc"
'Close the original document without saving changes
oDoc.Close SaveChanges:=False
'Get a handle on the next file in your source folder
oFile = Dir
Loop
End Sub

I personally prefer to work with the Scripting.FileSystemObject; it's generally easier to work with than parsing and recombining the output of the VBA Dir function. Add a reference to the Microsoft Scripting Runtime library, via Tools -> References....
I would suggest using the following functions :
Public Function GetFiles(ByVal roots As Variant) As Collection
Select Case TypeName(roots)
Case "String", "Folder"
roots = Array(roots)
End Select
Dim results As New Collection
Dim fso As New Scripting.FileSystemObject
Dim root As Variant
For Each root In roots
AddFilesFromFolder fso.GetFolder(root), results
Next
Set GetFiles = results
End Function
Private Sub AddFilesFromFolder(folder As Scripting.folder, results As Collection)
Dim file As Scripting.file
For Each file In folder.Files
results.Add file
Next
Dim subfolder As Scripting.folder
For Each subfolder In folder.SubFolders
AddFilesFromFolder subfolder, results
Next
End Sub
This takes a path, or a Scripting.Folder object (or an array of either), and returns a collection of File objects for each file in all the subfolders for the passed in folder(s).
Then you can write your code as follows:
Sub ConvertReturns()
'This Sub loops through docx files in a folder recursively, opens each file, finds manual line breaks, replaces each with a paragraph return, saves changed file to a new folder, closes original file.
Dim targetFolder As String
Dim oFile As Scripting.file, oFso As New Scripting.FileSystemObject
Dim oDoc As Document, oRng As Range
Dim fileName As String, fileExtension As String
Dim targetPath As String
'Set paths to folders for original and converted files on user's hard drive.
Const sourceFolder = "C:\Users\Administrator\Desktop\Unprocessed\"
targetFolder = "C:\Users\Administrator\Desktop\Processed\"
'Repeat the following code for each File object in the Collection returned by GetFiles
For Each oFile In GetFiles(sourceFolder)
'This handles any Word Document -- .doc and .docx
If oFile.Type Like "Microsoft Word*" Then
'Open the file
'.Path returns the full path of the file
Set oDoc = Documents.Open(fileName:=oFile.Path)
'Find all manual line breaks and replace them with paragraph markers
Set oRng = ActiveDocument.Range
With oRng.Find
.Text = "^l"
.Replacement.Text = "^p"
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchCase = False
End With
oRng.Find.Execute Replace:=wdReplaceAll
fileName = oFso.GetBaseName(oFile.Name)
fileExtension = oFso.GetExtensionName(oFile.Name)
targetPath = oFso.BuildPath(targetFolder, fileName & "_Converted." & fileExtension)
'Save the changed document with the same name but appended with "_Converted" in your target folder
oDoc.SaveAs targetPath
'Close the original document without saving changes
oDoc.Close SaveChanges:=False
End If
Next
End Sub
