Just to add a bit to cheyennedonna's excellent recommendations... I myself have recipes in one document, where each recipe starts on a new page. As cheyennedonna says, this makes it really easy to find a recipe in one file, rather than managing 200 files.

One hint, though. Set your document page size (or at least when printing it to PDF) to something like 4.25"x5.5" (essentially a quarter page) given the small screen on your Pocket eDGe. You may want to play with the exact settings with a document with only one recipe.

Dropbox, by the way, is a way so that if you drag and drop files into a dropbox folder on your PC, it will automagically appear on your eDGe without having to do anything. You need to install the dropbox software on your PC (using the link cheyennedonna posted) and on your eDGe (go to Library, pick "Store" in the top right dropdown box, then "Apps" and then look for it in the listing).
