I installed iFile for the main purpose of being able to move files between applications. For example, I want to be able to download a PDF from my company fileserver using NetPortal, then move it to the Documents folder of GoodReader so that I can view the PDF with that viewer instead of the default one. iFile gives me the ability to access the iPhone file system to move files around in this way. It gets around the iPhone restriction of each app only being able to access the files stored in its own "sandbox". However, there's a problem. Apple names each app folder with a cryptic hex code. To get around this, I set up iFile with bookmarks to the documents folder of the main apps I wanted to move files between. I had to go through each App folder one by one until I found the ones I wanted to bookmark. I have a lot of apps. It's been a while since I did this. Today I discover that none of those bookmarks work anymore. Folders don't exist. Does the iPhone change these cryptic folder names when I update? Is there a better alternative to iFile? Any other suggestions?
