Can you let me know what following lines doing?

set diskmb = ObjectManager.CreateExpression( " 'LogicalDisk.Free Megabytes;*.*' ")

I've never seen quite that syntax, but it looks like its calling and object in another library (objectmanager) and asking it to call methods on another object (logicaldisk) and return objects from them.
Alternatively, it may be evaluating an expression where logicaldisk.free etc. are known variables (rather than it calling objects)

The objects returned are put into diskmb and diskpct.

With out more supporting code I can't quite tell what its pupose is, other than to return information about a disk or disks.

It sets up a reference for you to LogicalDisk Object so you can do farther work with it. After you have it set up you then can use that object. I also didn't see this kind of a code before. Do you have a DLL library ? How do you create an instance of this object ? Do you have it referenced ? If not this may not work.

If its in VBScript then there are no references, so thats not an issue so long as the objectmanager object is set to something using createobject, i.e

set objectmanager=createobject("prog.id")
