+# POSIX file access example
+
+This example runs several file system tests on ESP8266.
+It uses fs-test library to perform file operations test. fs-test library uses
+only POSIX file functions so can be run on host system as well.
+
+Currently included tests:
+ * File system load test. Perform multiple file operations in random order.
+ * File system speed test. Measures files read/write speed.
