FileAPI

This API is only available on the host.

For more information, see Pings.

FileAPI allows your avatar to access files in isolated folder.

FileAPI is available as global file variable.

Security

FileAPI is fully isolated in your data folder. It is located in your Figura folder, so, default path for it would be figura/data. FileAPI can't access any files or directories out of this folder, even when using symbolic links. Attempt to access file or directory outside data folder will result in error. Every used path in methods is relative to data folder.
