Is there a way for docs to go to search directories on the card instead of bringing all files back in one place?

I have 100's of files on the SD card, and don't want have to reorganize them using the docs to go categories. How do you guys handle this?

Is there a way to do it in zlauncher? I can't seem to associate .doc, .xls, and .ppt with the docs to go application when clicking the file directly from zlauncher.
