Every method in the fs module has synchronous as well as asynchronous forms. Asynchronous methods take the last parameter as the completion function callback and the first parameter of the callback function as error. It is better to use an asynchronous method instead of a synchronous method, as the former never blocks a program during its execution, whereas the second one does. All possible values have been mentioned below. It defaults to , readable and writeable.

Recent improvements in both the performance and scalability of shared-nothing, transactional, in-memory NewSQL databases have reopened the file question of whether distributed metadata for hierarchical file systems can be managed using commodity databases. HopsFS also has system latency for many concurrent nodes, and no downtime during failover. Finally, as metadata is now stored in a commodity database, it can be safely extended and easily exported to external systems for online analysis and free-text search.


From a programming perspective, the NuttX file system appears very similar to a Linux file system.
