Looping all VM machines - file opeartions

Hi all,

I'm using with vSphere Guest SDK Documentation in .NET C#.

I'm trying to loop all my vm machines in my ESXi and to do some file operations , I'm confused but I didn't find how I can loop all machines and use file manager object, there are lot of examples using virtualmachine object inherited from entity object. No file operation with those object.

I know VIX+VI where combind in the last SDK release.

any suggestions ?

Thanks In Advanced.
