File System

Working with non-structured data
Dynamics Mobile Apps can store and read files. The files are meant to be used to store unstructured data.
Dynamics Mobile SDK provides a class called FileService, which allows the developer to work with files in a transparent way.
The FileService allows the developer to :
  • create/write new files
  • read the content of files
  • delete existing files
  • check if specific filename exists
  • organize the files in folders
While the FileService API is the same for both mobile and backend apps, there is a slight difference in the behaviour between the two:
