Batch Loader and Folders_g Question

Question

I would like to use Batch Loader to load a large number of images into WCC. I am also using Folders_g in my implementation, and would like to instruct batch loader during asset loading run-time which folder in /Contribution Folders/ to place the asset. Does anyone know what the batch load file key / value pair is to make this happen?
Would I use something like this: (using dCollectionPath)
Action = insert
dDocTitle=Test Image
dDocAuthor=sysadmin
dSecurityGroup=Public
dDocType=Document
dInDate=10/25/10 9:58 AM
primaryFile=C:/Files/Test Image.doc
dCollectionPath=/Contribution Folders/images
<<EOD>>
Thank you,
Randy

Good Morning,
Thank you Anand and Srinath for helpful answers. Yes, the xCollectionID does work and I have it loading into the correct folder using that approach. However, I have several folders under the root /Contribution Folders hierarchy, and determining the xCollectionID of each or these subfolders prior to Batch Loader runtime and mapping the IDs to each of the nodes in the Batch Load File will be tedious. Furthermore, I will be building the Batch Load File on at least four different environments i.e. DEV, TEST, STAGING, and PRODUCTION, and determining xCollectionIDs for several folders across these environments will add even more complexity. I can do it, but was hoping for an easier path.
I am open to any more suggestions / ideas following your digestion of the previous information.
Let me throw one other question out there. Let's say I am able to load all my assets into the several folders in my folders_g hierarchy in my DEV environment using the mapping of xCollectionID. Am I able to migrate that folder structure with loaded assets downstream into TEST, STAGING, and PRODUCTION using some out of the box UCM utility? Does something like that exist?
Thank you,
Randy
