I've learned a trick that I wanted to share. This is to load a folder of files into an App that supports sub folders (like a PDF reader, picture viewer, CBR/CBZ reader) It won't work in Apple apps that have a direct iTunes link..only through 3rd Party apps that use the iTunes file sharing. (I believe it only works with a Mac, but Windows might have a way to do it.) On the Mac, put the files (jpgs, pdfs, whatevs) in a folder. (we'll call it Test_Folder) add a .pkg extension to the folder (so Test_Folder.pkg) This turns the folder into a mac package file. It's still a folder, but the Mac OS treats it as a single file. Drag that folder into the App's window in iTunes. Optional: In the iTunes window, edit the file name to delete .pkg. This isn't necessary but it cleans the list up some. On your i Device, go to the App and enjoy the new sub-folder. This takes advantage of the Mac seeing a .pkg file as a file, but iOS (and Windows) seeing it as a folder.
