I am running a macro in Excel 2000 that does a "save as". If the file already
exists and the full filename (including drive and path) is greater than 149
characters, then Excel crashes. Apart from the obvious of shortening the
directory or file names, does anyone know how to stop this happening?

Example code below:

Private Sub CommandButton1_Click()

' This line works (149 characters)
ActiveWorkbook.SaveAs
"C:\abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrst uvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqr stuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijkl.xls "

' This line works (150 characters) if file does not already exist
ActiveWorkbook.SaveAs
"C:\abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrst uvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqr stuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklm.xl s"

' This line crashes (150 characters) if file already exists
ActiveWorkbook.SaveAs
"C:\abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrst uvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqr stuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklm.xl s"

End Sub
