update-mime-database not recognized

[John Levin]

Hi,

I'm going through the post-install steps for KDE 4, using 
KDE-win-installer 0.8.6

When I try running the update-mime-database command, I get
"'update-mime-database' not recognized as an internal or external 
command, operable program or batch file."
I have set the path; I can't find any package entitled 
'update-mime-database' - what am I missing?

TIA

John
