Combine Multiple Excel Workbooks into one Workbook with multiple sheets - vba

Question

I have about 70 different excel files that I need to combine into one master workbook. I would like each excel file to get its own worksheet in the master workbook. The name of the worksheet generated in the master workbook doesn't matter.
I retrieved this code off of another website, but cannot make it work for my needs. This code stipulates that all files to be combined are located in the same directory. I have them located here "C:\Users\josiahh\Desktop\cf"
Below is the code as it is now
Sub GetSheets()
Path = "C:\Users\dt\Desktop\dt kte\"
Filename = Dir(Path & "*.xls")
Do While Filename <> ""
Workbooks.Open Filename:=Path & Filename, ReadOnly:=True
For Each Sheet In ActiveWorkbook.Sheets
Sheet.Copy After:=ThisWorkbook.Sheets(1)
Next Sheet
Workbooks(Filename).Close
Filename = Dir()
Loop
End Sub

This is tested and works as expected. You would be wise to use Option Explicit and declare your variables appropriately in the future, although that did not cause any problems with your code.
As indicated in comments above, the likely failure is that the argument you're passing to the Dir function is unnecessarily restrictive:
=Dir(path & "*.xls") will look ONLY for files ending exactly in ".xls", and will not account for newer file formats. To resolve that, do =Dir(path & "*.xls*")
Code below:
Option Explicit
Const path As String = "C:\Users\dt\Desktop\dt kte\"
Sub GetSheets()
Dim FileName As String
Dim wb As Workbook
Dim sheet As Worksheet
FileName = Dir(path & "*.xls*")
Do While FileName <> ""
Set wb = Workbooks.Open(FileName:=path & FileName, ReadOnly:=True)
For Each sheet In wb.Sheets
sheet.Copy After:=ThisWorkbook.Sheets(1)
Next sheet
wb.Close
FileName = Dir()
Loop
End Sub
