I've been trying to include iOS in my daily workflow for years now and despite my best efforts, I can't seem to get it right. I think it might be a mindset, perhaps I need a new way of thinking. My problem is this : On my Mac I'll have a folder called "university" and within this folder I'll have subdirectories for each subject, for example : English, Philosophy and Law. Within each of those subdirectories I will have a further set of directories for each lecture : Lecture 1, Lecture 2, Lecture 3 etc. Lastly within each lecture folder I'll have a collection of files - PDFs, Pages, Word, JPG etc. It's easy to work with the documents in this logical structure on my Mac. I simply open the files, edit them, save them and close them. The documents are all related and they stay together in that folder. I use DropBox to keep them synced between my iMac and my MacBook Air. The problem comes in with iOS. I really want to be able to continue working on my iPad where I left off on my Macs. I've tried simply accessing the documents using the DropBox app or GoodReader (and many similar apps) and then opening the document in the related app (e.g. : opening Pages documents in Pages), but the problem is obviously that a copy of the file is made instead of it being edited directly. Saving the file back to DropBox is more difficult than it should be since you have to find the file again and then overwrite it, and the copy of the file usually stays in the app I was editing it in making duplicate files that I often forget about - later on I can't remember which is the newest version of that file. I like the idea of iCloud, especially when using Pages, and I'm aware of the rumours that iOS 8 will include a Preview app that will (hopefully) mean that PDFs can be synced with iCloud too. But this doesn't really solve my problem. iCloud only allows for the creation of single-level directories, meaning that I won't be able to logically arrange my files as described above. Whats more, if I figure out a new way of arranging my files (that you hopefully have suggestions for) the files of different formats will be scattered across many different apps - and I'm sure I'll forget about some of them (which is catastrophic). I know I'm not the only one facing this dilemma. It's the age old complaint that iOS needs a centralised file system. We're already on iOS 7 and there's no sign of one on the horizon. In light of that, I'm sure some of you have figured it out - if so, please lend me your wisdom. I really want to make this work (preferably using iCloud).
