Why would that be any easier then simply having your viewer flip from page to page using separate files? Just put the files in a directory and send. There is no "difficult process to add files" like you seem to be implying. You can open your document\HP Connectivity Kit\Content\<your_app>\ and add the files like any other folder. Or do the same thing by dragging them into the folder in the connkit file browser. Or load them in a folder in a zip. Or directly add it to the folder in the HP Connectivity Kit\Calcs\<your calc name> directory.

You are correct that you can't yet drag to an individual application directly in the calculator tree, but there are at least 4 other ways to do it directly right now.

Well, since you are returning a list of numbers representing bytes... it wouldn't.

Quote:By the way, even "G1:=AFilesB(...)" doesn't work with a normal PNG.

AFilesB(...) returns the size of the file as a number.


It seems like you are asking to be able to do the equivalent of take 100 video files, combine them into one single large file, and then be able to later use that single file as if they were separate. I've never seen a single program that does that as it doesn't really make sense. The closest thing I've seen is some of the comic book readers which just are a compression archive with named files in sequence...
