If the file or directory does exist already, it'll return true: Path tempFilePath = Files.createTempFile("baeldung", "exist-io") However, to make sure if a file or directory exists in Java legacy IO world, we can call the exists()method on Fileinstances: assertFalse(new File("invalid").exists()) If we're using Java 7 or a newer version of Java, it's highly recommended to use the modern Java NIO APIs for these sorts of requirements. ![]() It's even possible to not follow the symbolic links by passing an appropriate LinkOptionas the second argument: assertTrue(Files.exists(symbolicLink, LinkOption.NOFOLLOW_LINKS)) īecause the link itself exists, the Files.exists(Path) method returns true. Also, we can check if a Path is a symbolic link using the Files.isSymbolicLink(Path)method: Since the link target doesn't exist anymore, following the link won't lead to anything, and Files.exists(Path) will return false. Now if we delete the target of the link, the Files.exists(Path) will return false: leteIfExists(target) ![]() Path symbolicLink = Files.createSymbolicLink(symbol, target) ![]() Path symbol = Paths.get("test-link-" + ThreadLocalRandom.current().nextInt()) If file A has a symbolic link to file B, then the Files.exists(A) method returns true if and only if the file B exists already: Path target = Files.createTempFile("baeldung", "target") By default, the Files.exists(Path) method follows the symbolic links.
