Here i am giving one example to create New file in New 
Folder and to write a "Hello World" in that file

File System Object Model
----------------------------
set fso =createobject("scripting.filesystemobject")
set newfolder = fso.createfolder("C:\QTP",True)
Set newfile = newfolder.createtextfile("C:\QTP\Test1",True)
newfile.writeline("Hello World")
newfile.close


Try with tis..I hope it will work

Child objects.

that which you had written for Fikle system Objects.
