Hey Jeff,
I'm not 100% sure what you are asking. Here are a few answers, depending on what you're trying to accomplish...
Several files in folder are too large, need to be purged: the eTransmit tool will allow you to batch process a bunch of drawings. In the options dialog, you should make sure "purge" is selected. eTransmit will then open up each file, purge it, save it, and go to the next dwg on the list. This will reduce the file size for all the files in that folder, and you can choose what folder to place the new dwgs.
A couple of drawings have a bunch of blocks in them that you want to run wblock on to split out into different files - part 1: you really don't have to do this. Having a bunch of blocks in one file can make them much easier to manage than each block being its own file. (We totally used to do that, but new tools makes this less desirable). If you use Design center, browse to the file in question, and right click on it, and choose add to tool pallet - you'll automatically get a new tool pallet with all that dwgs blocks available. When you insert a block from the tool pallet, it only loads "that block" so your project DWG stays small. The new block pallet also does this well.
