Merge multiple Excel files into a new Excel file - vba

Question

I know the question has been asked so many times already, and I have tried to use Google to search the interest but failed to find the correct code. ( Trust me, I am not a taker).
Anyway, the idea is to run a script to merge all Excel files (CAD,GBP,JPY,USD) into a new Excel file (tab shows name "CAD","GBP", "JPY","USD") in the current folder. I have written the following script to merge Excel files, but it does not even work.
Sub CombineWorkbooks()
Dim Path As String
Dim FileName As String
Dim Wkb As Workbook
Dim WS As Worksheet
Application.EnableEvents = False
Application.ScreenUpdating = False
Path = "X:\PATH\TO\EXCEL\FILES"
FileName = Dir(Path & "\*.xls", vbNormal)
Do Until FileName = ""
Set Wkb = Workbooks.Open(FileName:=Path & "\" & FileName)
For Each WS In Wkb.Worksheets
WS.Copy After:=ThisWorkbook.Sheets(ThisWorkbook.Sheets.Count)
Next WS
Wkb.Close False
FileName = Dir()
Loop
Application.EnableEvents = True
Application.ScreenUpdating = True
End Sub

You only have one small mistake.
Change:
Wkb.Close False
To:
Wkb.Close SaveChanges:=False
Here's my full, tested and working solution:
Sub CombineWorkbooks()
Dim Path As String
Dim FileName As String
Dim Wkb As Workbook
Dim WS As Worksheet
Application.EnableEvents = False
Application.ScreenUpdating = False
Path = "X:\PATH\TO\EXCEL\FILES"
FileName = Dir(Path & "\*.xls", vbNormal)
Do Until FileName = ""
Set Wkb = Workbooks.Open(FileName:=Path & "\" & FileName)
For Each WS In Wkb.Worksheets
WS.Copy After:=ThisWorkbook.Sheets(ThisWorkbook.Sheets.Count)
Next WS
Wkb.Close SaveChanges:=False
FileName = Dir()
Loop
Application.EnableEvents = True
Application.ScreenUpdating = True
End Sub
If this doesn't work for you, please give more detail about the results and/or errors. A list of the file names in the folder would also be helpful.
If this does work for you, please remember to mark this as your answer, so others will know you have your solution. Thanks!
