What is It?

//Determine if a file or directory
//exists at that path
Files.exists(pathObject);

//Is that object a directory?
Files.isDirectory(pathObject);

//Is that object a regular file?
Files.isRegularFile(pathObject);
  

How Big is It?

Files.size(pathObject);  

Returns size of file in bytes

Throws IOException on a directory
or missing file

Copy and Move

Path source = Paths.get("/home/codio/workspace/dir1/file1.txt");
Path dest = Paths.get("/home/codio/workspace/dir2/file2.txt");

//copy file
Files.copy(source, dest);
//move (rename) file
Files.move(source, dest);

Will throw FileAlreadyExistsException
if destination exists

We can tell it to overwrite
(see documentation)

Delete

Files.delete(pathObject);

Will throw DirectoryNotEmptyException
if deleting a non-empty directory

Create

Files.createFile(pathObject);
Files.createDirectory(pathObject);

Will throw FileAlreadyExistsException
if destination exists
