This path can be created in Directory Opus, and I think other programs as well, but not xplorer2:
C:\-----10--------20--------30--------40--------50\-------60--------70--------80--------90-------100\------110-------120-------130-------140-------150\------160-------170-------180-------190-------200\------210-------220-------230-------240-------250\------260-------270-------280-------290-------300
Not sure exactly what is the maximum path length that xplorer2 will create, but this one failed:

Of course I had followed Microsoft's instructions for enabling long path support -
