When you install Windows 98, this prompt does not appear and newer files replaced by Windows 98 Setup are automatically backed up to your hard disk for compatibility purposes.
For example, if you upgrade a Windows 95-based computer that uses a newer version of the Commdlg.dll file to Windows 98, the newer Commdlg.dll file is backed up and the older Commdlg.dll file is copied to your computer.
