Create folder and subfolder - excel

Question

I have an Excel file with hundreds of Customer names and several article numbers.
I want to check if a folder with selected customer name exists and create a folder if it is missing.
Once the customer folder is found or created, check if there is a folder for each article number and if it is missing, create one.
I found code that seems to do all that and more posted by Scott Holtzman.
I have referenced Microsoft Scripting Runtime as the code requests.
Both of the "If not" statements are marked red and the pop-up window only says "Compile error".
I checked the syntax of "If not" statements and it seems to be correct.
'requires reference to Microsoft Scripting Runtime
Sub MakeFolder()
Dim strComp As String, strPart As String, strPath As String
strComp = Range("A1") ' assumes company name in A1
strPart = CleanName(Range("C1")) ' assumes part in C1
strPath = "C:\Images\"
If Not FolderExists(strPath & strComp) Then
'company doesn't exist, so create full path
FolderCreate strPath & strComp & "\" & strPart
Else
'company does exist, but does part folder
If Not FolderExists(strPath & strComp & "\" & strPart) Then
FolderCreate strPath & strComp & "\" & strPart
End If
End If
End Sub
Function FolderCreate(ByVal path As String) As Boolean
FolderCreate = True
Dim fso As New FileSystemObject
If Functions.FolderExists(path) Then
Exit Function
Else
On Error GoTo DeadInTheWater
fso.CreateFolder path ' could there be any error with this, like if the path is really screwed up?
Exit Function
End If
DeadInTheWater:
MsgBox "A folder could not be created for the following path: " & path & ". Check the path name and try again."
FolderCreate = False
Exit Function
End Function
Function FolderExists(ByVal path As String) As Boolean
FolderExists = False
Dim fso As New FileSystemObject
If fso.FolderExists(path) Then FolderExists = True
End Function
Function CleanName(strName as String) as String
'will clean part # name so it can be made into valid folder name
'may need to add more lines to get rid of other characters
CleanName = Replace(strName, "/","")
CleanName = Replace(CleanName, "*","")
' etc...
End Function

Take a look at the below example, it shows one of the possible approaches using recursive sub call:
Option Explicit
Sub TestArrays()
Dim aCustomers
Dim aArticles
Dim sCustomer
Dim sArticle
Dim sPath
sPath = "C:\Test"
aCustomers = Array("Customer01", "Customer02", "Customer03", "Customer04", "Customer05")
aArticles = Array("Article01", "Article02", "Article03", "Article04", "Article05")
For Each sCustomer In aCustomers
For Each sArticle In aArticles
SmartCreateFolder sPath & "\" & sCustomer & "\" & sArticle
Next
Next
End Sub
Sub TestFromSheet()
Dim aCustomers
Dim aArticles
Dim i
Dim j
Dim sPath
sPath = "C:\Test"
With ThisWorkbook.Sheets(1)
aCustomers = .Range(.Range("A1"), .Range("A1").End(xlDown)).Value
aArticles = .Range("B1:B10").Value
End With
For i = LBound(aCustomers, 1) To UBound(aCustomers, 1)
For j = LBound(aArticles, 1) To UBound(aArticles, 1)
SmartCreateFolder sPath & "\" & aCustomers(i, 1) & "\" & aArticles(j, 1)
Next
Next
End Sub
Sub SmartCreateFolder(sFolder)
Static oFSO As Object
If oFSO Is Nothing Then Set oFSO = CreateObject("Scripting.FileSystemObject")
With oFSO
If Not .FolderExists(sFolder) Then
SmartCreateFolder .GetParentFolderName(sFolder)
.CreateFolder sFolder
End If
End With
End Sub
Sub TestArrays() checks and creates folders for customers and articles from the hardcoded arrays, and Sub TestFromSheet() gets customers and articles from the first worksheet, as an example customers range from A1 up to the last element, so it should be more than one element there, and articles set to fixed range B1:B10, like shown below:

The StrComp Issue
You cannot use StrComp, its a reserved word, actually a string function. I lost about 15 minutes the other day on this issue.
VBA says: Returns a Variant (Integer) indicating the result of a string comparison.

If you want to shorthand a bunch of that code, use MKDIR to create each level of folder\subfolder with error pass-over.
Option Explicit
Sub main()
Dim pth As String
pth = "c:\test\abc\123\test_again\XYZ\01-20-2019"
'folder may or may not exist
makeFolder pth
'folder definitely exists
End Sub
Sub makeFolder(fldr As String)
Dim i As Long, arr As Variant
'folder may or may not exist
arr = Split(fldr, Chr(92))
fldr = arr(LBound(arr))
On Error Resume Next
For i = LBound(arr) + 1 To UBound(arr)
fldr = Join(Array(fldr, arr(i)), Chr(92))
MkDir fldr
Next i
On Error GoTo 0
'folder definitely exists
End Sub

To rename an existing file to a new location WITH creation of all subdirectories, you can use:
File_Name_OLD = File_Pad_OLD & "Test.txt"
File_Pad_NEW = "e:\temp\test1\test2\test3\"
File_Name_NEW = File_Pad_NEW & "Test.txt"
X = File_Pad_NEW
A = 1
Do Until A = 0
A = InStr(X, "\")
Y = Y & Left(X, A)
X = Mid(X, A + 1)
If Dir(Y, 16) = "" Then MkDir Y
Loop
Name File_Name_OLD As File_Name_NEW
This is creating the new path with subdirectories and renames the old file to the new one.
