The SD card tries to select the SD card path if one exists. This is not guaranteed to work and can differ based on OS version and device manufacturer. Selecting the SD card will toggle between any detected SD card paths and the default application path (so it also provides a way to go back to the default). Tapping the folder icon lets users browse for their own folder. When it comes to the folder path for an SD card, that is a complex topic. Sometimes MobileSheets can know what the path represents, but it's also not guaranteed (if you tap the SD card, it can guess that it might be an SD card path, or it could be a removable thumb drive, or an external USB hard drive). I wouldn't want to hide the folder path from the user, as it's important in some cases to know what the full path is, but perhaps I can try to add some kind of indicator that MobileSheets believes an SD card was picked (or some other kind of removable storage). In general, I don't really want most users messing with the storage location unless they know what they are doing because it just increases the amount of support requests I get from users who change settings without understanding them. That's partly because, as you said, there isn't a lot of information on the dialog itself, and partly because users change this setting without understanding the way the file system works on Android, which is based on Linux.
