@mikeo007: Yes, it would make sense for downloaded files to go to apps that have registered for that file type. That can't be the whole rule however. For example, where does a file of an unregistered type go? Also, what happens when multiple apps are registered for the type of the downloaded file? Does the file get duplicated to all registrants, or is one picked by iOS somehow, or ( hope, hope) is there some way for me to control where it goes?
@jaguarr40: It's an iPad which I use for writing. I have need to download a fair number of web files.
@avmsam: iOS definitely does have a UNIX-based file system. Google "iOS file system" and you get lots of documentation. It's just that Apple tries to hide that fact in iOS for useabilty reasons.
I have one example where a downloaded document file wound up in a very wrong place. It looked like iOS decided to place it based on the non-extension part of the downloadedfile name, and thereby caused me some trouble to deal with it.
BTW, I'm new to this forum, but I think the search function here sucks hind tit. Lack of a good search caused me to double post this question. Ignore the other post.
