Automatically detect and change drive letter

Good Afternoon Guys

On a userform with a button to open another workbook and close the current one, I use this code..... It works fine, however it will be used by different people and may need to sit on different drive for some.

The folder structure will remain the same but how do I change it to automatically detect and change the path for the different drives

Private Sub cmdhands_Click()
    Workbooks.Open Filename:="H:\Compliance Information\H&S\H&S Access.xls"
    ThisWorkbook.Close SaveChanges:=True
End Sub

Many thanks for your help
