Copy and paste an excel file with variable name

What I want to design is a file which can copy and paste a file in the active worksheet. However, this file will be updated daily and also change its name. Therefore, I'd like to refer to a dynamic name so to say.

Sub stackoverflow()

' copy workbook to new worksheet

    Workbooks.Open Filename:= _
    "/Documents/Documenten/movementreport202001075.xlsx"
    Cells.Select
    Selection.Copy
    Windows("test").Activate
    ActiveSheet.Paste

End Sub

For instance, the "20200107" can be "20200108.xlsx" tomorrow. So it is dependent on the date, time and seconds you download the report.
