Molden is a general molecular and electronic structure processing program.
Molden program has been tested on different platforms, namely Linux, Windows NT, Windows95, Windows2000, WindowsXP, MacOSX, Silicon Graphics IRIX, Sun SunOS and Solaris.
The differences are largely in computational cost, with GAFF being very expensive.
Molden can read several file formats with crystal information.
