I noticed something odd about Pages. I have my iDisk mirrored on my Desktop, and have it set to automatically syncronize. When I save a Pages document, the Finder window shows me that it is not synchronizing one file, but 8 or 9 files! In other words, the .pages file format is just like the .rtfd file format, in that it is really a folder that contains multiple files, and each file contains different elements of the document, such as text, thumbnails, graphics, and whatever else.
I found it disturbing a couple of years ago when I noticed that Apple was using a folder to enclose the same information as Microsoft encloses in one file; viz., Apple's TextEdit (and now Pages) save documents with rich text and photos in the RFTD format (which is really a folder) yet Microsoft Word (and WordPad) save the same documents in just one file. For that matter, I think WordPerfect saves rich text with graphics in just one file as well.
Why did Apple choose to go this way? I don't understand the benefits or efficiency of such a design. I suppose Apple's way might be better, but I would be very interested to know why. Does anyone know about this who can enlighten me on the subject?
