Hi All, It has been brought to my attention that the older BT_fileManager saved files under the NSCaches directory, not the NSDocuments directory. Now with a BT3.0 project, users are loosing data that was stored by the BT_fileManager, does anyone know if this is a bug in BT_fileManager class with BT3.0? Thanks, Jake

1. Put user data in the <Application_Home>/Documents/. User data is any data that cannot be recreated by your app, such as user documents and other user-generated content. Use this directory to store critical user documents and app data files. Critical data is any data that cannot be recreated by your app, such as user-generated content. The contents of this directory can be made available to the user through file sharing. The contents of this directory are backed up by iTunes. 2. Put data cache files in the <Application_Home>/Library/Caches directory. Examples of files you should put in this directory include (but are not limited to) database cache files and downloadable content, such as that used by magazine, newspaper, and map apps. Your app should be able to gracefully handle situations where cached data is deleted by the system to free up disk space. 3. Put temporary data in the <Application_Home>/tmp directory. Temporary data comprises any data that you do not need to persist for an extended period of time. Remember to delete those files when you are done with them so that they do not continue to consume space on the user’s device. https://developer.apple.com/library/mac/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html -- Niraj
