@happybeing, so as you’ve seen. fetch simply returns the File object. whereas open can be used to open and modify a file (using the openMode argument):
CONSTANTS.NFS_FILE_MODE_OVERWRITE: Replaces the entire content of the file when writing data.
CONSTANTS.NFS_FILE_MODE_APPEND: Appends to existing data in the file.
CONSTANTS.NFS_FILE_MODE_READ: Open file to read.
can fetch() be used and then allow access to file metadata?
