look in the SYS folder, inside any subfolder. take OS for example. in VK is it in sys\23xxx\shared\common\OS. look inside one of the folders. anything that is a folder with a name of something.dll that contains:

imageinfo.bin
imageinfo.txt
S000
S001
S002
etc

is a module. they are cooked in at cooking time, a folder that is called browser.dll is made up of those files. when cooked it manifests as a dll in \windows\ called browser.dll... modules load faster than files. you will notice some files that are just plain old dll's and not modules. I don't know all the technical details ... the point is try using dump sorter to delete every file in the sys that has the name of the folder it resides in. See if that stops your messages about module duplicates..
