I have lots of files in cloud storage that I want to access remotely but not have them eating space on my phone. Examples include an MP3 file I downloaded at work and want to listen to on my commute or an M3u I want to stream. I might have a reference I'm studying in html such as the excellent quick reference for iOS gestures from National Braille press, or documentation for a Braille display.
These are files that open fine in Safari. But when I put them in cloud storage, I can sometimes open them and sometimes not.
For example, if I try to open an MP3 in dropbox, it plays just as if I found it online in Safari. But if I try to open it in OneDrive, I end up having to do "open with" and choose an application like Downcast, because Safari is not on the open-with list.
HTML files are also hard to open in Dropbox, which has its own viewer. The google drive app keeps getting updated, so it used to not play music; now it does. I guess what I really want to know is whether someone has found one solution for stashing files they want to access remotely, especially html and audio; files that built-in functions in iOS can already natively access.
