The project array is an array stored as json that sits at the top-level of the project folder. It contains a set of standard fields (array keys), but can be extended to contain arbitrary fields.
The relative path to the file constining the json encoded array (within the project folder) is:
/lcw_project.json
Due to the large size of the array when it contains indexes of handlers and their dependencies, the project array can optionally be stored as as an Encoded Array.
/lcw_project.array
We use the "lcw_" prefix to make these files easier to find using Spotlight or similar, and to distinguish the files from other software.
