Some FileSystem functions are able to read from but not write to other locations. Currently FileSystem. UTF8 -- Standard readable format. Base64 -- Binary, radix representation. These values can be used to define how sessions work on iOS. If the task completes while the application is in background, the Promise will be either resolved immediately or if the application execution has already been stopped once the app is moved to foreground again.
