How to copy the folders using 'File' in installer script?

For example:

If my script exists in a folder "C:\code\installer\"
And my $INSTDIR is setto "C:\sampleProject".
and my sample project have multiple features...each feature needst to copy in to diffrent folder. ex:- "C:\sampleProject\fea1", "C:\sampleProject\fea1\", "C:\sampleProject\fea2\"...etc.,
And the source for all these features are needs to take from "C:\code\fea1", "C:\code\fea2"...etc.,
is this possiable to copy using 'File'? if yes, how? if no, is there any otherway to do this.

Thanks.
