Set permissions on a user or group basis. This is especially useful for access permissions on files and folders as part of the Digital assets management (FAL) of the core.
Read more about FAL access permissions in the permission chapter of the core API document, but find some examples below:
# Allow to create and upload files on all storages
permissions.file.default.addFile = 1
# Allow to add new folders if user has write permissions on parent folder
permissions.file.default.addFolder = 1
# Allow to edit contents of files on FAL storage with uid 1
permissions.file.storage.1.writeFile = 1
