How to list all the file using go shell ipfs

@hector I only saw this 2, Please advise. Thanks

// Add imports files to the cluster from the given paths.

Add(ctx context.Context, paths []string, params *api.AddParams, out chan<- *api.AddedOutput) error

// AddMultiFile imports new files from a MultiFileReader.

AddMultiFile(ctx context.Context, multiFileR *files.MultiFileReader, params *api.AddParams, out chan<- *api.AddedOutput) error

@hector do you have any comment?
