VB macro Excel script should copy entire folder data - vba

Question

Background : approx. 300 Excel surveys (with multiple sheets) should be centralized in 1 single excel.The macro is ready.
Goal : although the Macro is ready and able to copy the desired data from the Survey excel,I do not have the possibility to copy all 300 surveys at once ( I have to go 1 by 1 through all the surveys)
Question : is it possible to ask the macro to target copy from a specific network path and hereby to copy all the 300 excel workbooks?
Macro script :
Function bIsBookOpen(ByRef szBookName As String) As Boolean
On Error Resume Next
bIsBookOpen = Not (Application.Workbooks(szBookName) Is Nothing)
End Function
Sub Start()
currwb = ActiveWorkbook.Name
If bIsBookOpen("PERSONAL.XLSB") Then
Windows("PERSONAL.XLSB").Visible = True
ActiveWindow.Close
End If
If Workbooks.Count > 1 Then
MsgBox " To many files open... " & Workbooks(1).Name
Else
Application.Dialogs(xlDialogOpen).Show
Response = MsgBox("Weiter mit 'IT-Personal'?", vbYesNo)
If Response = vbYes Then
Windows(currwb).Activate
Call CopyForm
End If
End If
End Sub

To loop through files in a folder,
Sub LoopThroughFiles()
Dim path As String
Dim filename As String
Dim wb As Workbook
path = "" 'your folder path here
filename = Dir(path & "*.xls")
While (filename <> "")
Set wb = Workbooks.Open(path & filename)
'Your code goes here
wb.Close
filename = Dir
Wend
End Sub
