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:
Feature | Backend App | Mobile App |
Storage Type | Cloud storage | Local device file system |
Access by other apps | Yes | No |
Access by external apps/systems | No | No |
Access from other app users | Yes | No |
Access from other app areas | No | No |
Deleted after app uninstall | No | Yes |
Max file size | 6Mb | 500Kb |
File Storage Size Quota | 50MB | limited by the device storage size |
