Although I specify one special destination folder to backup my device, I keep finding RIM, Blackberry, MediaSync, and seemingly related BB files and "stuff" all over my otherwise meticulously organized Windows 7 C: drive. And I don't even sync up my calendar or contacts with anything -- I like my Thunderbird contacts in their own separate world, and I just don't use another calendar.
I do regular "backups" at least every day and I find those backups by name in the folder I specify. I also follow the instructions from this wonderful site to backup my third party apps every week or so and know where to find that folder and I copy it to the same folder I keep my "regular" backups.
But I'm confused about, well, most everything else.

I
want to have everything that might someday be needed in that one folder (it's just the kind of girl I am.) (and heck, it just makes sense, no? especially when I want to make a backup of my most important PC files?) But the desktop folder keeps hiding things elsewhere. Might I need that stuff someday or should I just ignore it?
If this makes sense to anyone (bless you!) could you please tell me, if you're using Desktop Software 6.0 Bundle 2342 or similar, and Windows 7 if that is relevant, what specifications should theoretically be meaningful to make the simplest backups of your stuff, so that it is not in various hiding places all over your PC? Or if things unavoidably go elsewhere, might I need them?
Or in simple terms, how do you manage your backups? (without concern for synching calendars and contacts.)
I apologize if this is too vague or too complicated. I hope I'm not the only one who has come across seemingly related BB files on their PC and wondered how to manage them too. Thank you so much.
