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:
