Replace folder if same name

I want to create a folder where I will save the files. If a folder with a specific name already exists I want to replace this folder with a new, empty one. Dont know what to do with this Else thing. Im getting run time error 75 path/file access error.

Path = "\\ASD\"
d = Format(Date, "yyyymmdd")
f = "NBT Reports "
If Len(Dir(Path & d, vbDirectory)) = 0 Then
MkDir (Path & f & d)
ElseIf ???
End If
