The fs.access() method is used to test the permissions of a given file or directory. The permissions to be checked can be specified as a parameter using file access constants. It is also possible to check multiple file permissions by using the bitwise OR operator to create a mask with more than one file constant.Note: It is not recommended to use the fs.access() method to check for the accessibility of a file before calling fs.open(), fs.readFile() or fs.writeFile(), because it introduces a race condition since the file state may be changed by other processes after the test....
