As per Apple documentation: https://developer.apple.com/library/ios/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html#//apple_ref/doc/uid/TP40010672-CH2-SW28 app's documents folder data can be shared/sync.
As per appcelerator documentation: http://docs.appcelerator.com/platform/latest/#!/guide/Filesystem_Access_and_Storage Ti.Filesystem.applicationDataDirectory can only accessible by app itself. If a file is added in app's Documents folder using
var f = Ti.Filesystem.getFile(timelogsData,'errors.log');f.write(data);
It can't sync/share it is only accessible by app itself.
We need an ability to create file inside Downloads folder and/or ability to create file inside App's Documents folder that can be share/sync.
