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:
