There are some filing system nodes around, check the flows site. Otherwise you can add a reference to the fs node library to the globals section in settings.js and then use global.get in a function. You can then use fs inside the function and just use the node.js functions.

fs-ops-access - Test existence and accessibility of a file or directory
