  - createTempDir
```
public static File createTempDir()
```
    Atomically creates a new directory somewhere beneath the system's temporary directory (as defined by the java.io.tmpdir system property), and returns its name.
    Use this method instead of File.createTempFile(String, String) when you wish to create a directory, not a regular file. A common pitfall is to call createTempFile, delete the file and create a directory in its place, but this leads a race condition which can be exploited to create security vulnerabilities, especially when executable files are to be written into the directory.
    This method assumes that the temporary volume is writable, has free inodes and free blocks, and that it will not be called thousands of times per second.
    
    Returns:
    the newly-created directory
    
    Throws:
    
    IllegalStateException - if the directory could not be created
  - touch
```
public static void touch(File file)

```
    Creates an empty file or updates the last updated timestamp on the same as the unix command of the same name.
    
    Parameters:
    file - the file to create or update
    
    Throws:
    
    IOException - if an I/O error occurs
  - createParentDirs
```
public static void createParentDirs(File file)
                             throws IOException
```
    Creates any necessary but nonexistent parent directories of the specified file. Note that if this operation fails it may have succeeded in creating some (but not all) of the necessary parent directories.
    
    Throws:
    
    IOException - if an I/O error occurs, or if any necessary but nonexistent parent directories of the specified file could not be created.

        File to)
                 throws IOException
```
    Moves a file from one path to another. This method can rename a file and/or move it to a different directory. In either case to must be the target path for the file itself; not just the new name for the file or the path to the new parent directory.
    
    Parameters:
    from - the source file
    to - the destination file
    
    Throws:

    Streams lines from a File, stopping when our callback returns false, or we have read all of the lines.
    
    Parameters:
    file - the file to read from
    charset - the charset used to decode the input stream; see Charsets for helpful predefined constants
    callback - the LineProcessor to use to handle the lines
    
    Returns:
    the output of processing the lines
    
    Throws:
    
    IOException - if an I/O error occurs
  - readBytes
```
public static <T> T readBytes(File file,
              ByteProcessor<T> processor)
                   throws IOException
```
    Process the bytes of a file.
    (If this seems too complicated, maybe you're looking for toByteArray(java.io.File).)
    
    Parameters:
    file - the file to read
    processor - the object to which the bytes of the file are passed.
    
    Returns:
    the result of the byte processor
    
    Throws:
    
    IOException - if an I/O error occurs
  - hash
```
public static HashCode hash(File file,
            HashFunction hashFunction)
                     throws IOException
```
    Computes the hash code of the file using hashFunction.
    
    Parameters:
    file - the file to read
    hashFunction - the hash function to use to hash the data
    
    Returns:
    the HashCode of all of the bytes in the file
    
    Throws:
    
    IOException - if an I/O error occurs

  - map
```
public static MappedByteBuffer map(File file)
                            throws IOException
```
    Fully maps a file read-only in to memory as per FileChannel.map(java.nio.channels.FileChannel.MapMode, long, long).
    Files are mapped from offset 0 to its length.
    This only works for files <= Integer.MAX_VALUE bytes.
    
    Parameters:
    file - the file to map
    
    Returns:
    a read-only buffer reflecting file
    
    Throws:
    
    FileNotFoundException - if the file does not exist
    
    IOException - if an I/O error occurs

```
public static MappedByteBuffer map(File file,
                   FileChannel.MapMode mode)
                            throws IOException
```
    Fully maps a file in to memory as per FileChannel.map(java.nio.channels.FileChannel.MapMode, long, long) using the requested FileChannel.MapMode.
    Files are mapped from offset 0 to its length.
    This only works for files <= Integer.MAX_VALUE bytes.
    
    Parameters:
    file - the file to map
    mode - the mode to use when mapping file
    
    Returns:
    a buffer reflecting file
    
    Throws:
    
    FileNotFoundException - if the file does not exist
    
    IOException - if an I/O error occurs

public static MappedByteBuffer map(File file,
                   FileChannel.MapMode mode,
                   long size)
                            throws FileNotFoundException,
                                   IOException
```
    Maps a file in to memory as per FileChannel.map(java.nio.channels.FileChannel.MapMode, long, long) using the requested FileChannel.MapMode.
    Files are mapped from offset 0 to size.
    If the mode is FileChannel.MapMode.READ_WRITE and the file does not exist, it will be created with the requested size. Thus this method is useful for creating memory mapped files which do not yet exist.
    This only works for files <= Integer.MAX_VALUE bytes.
    
    Parameters:
    file - the file to map
    mode - the mode to use when mapping file
    
    Returns:
    a buffer reflecting file
    
    Throws:
    
    IOException - if an I/O error occurs
    
    FileNotFoundException

  - simplifyPath
```
public static String simplifyPath(String pathname)
```
    Returns the lexically cleaned form of the path name, usually (but not always) equivalent to the original. The following heuristics are used:
    - empty string becomes .
    - . stays as .
    - fold out ./
    - fold out ../ when possible
    - collapse multiple slashes
    - delete trailing slashes (unless the path is just "/")
    These heuristics do not always match the behavior of the filesystem. In particular, consider the path a/../b, which simplifyPath will change to b. If a is a symlink to x, a/../b may refer to a sibling of x, rather than the sibling of a referred to by b.

  - getFileExtension
```
public static String getFileExtension(String fullName)
```
    Returns the file extension for the given file name, or the empty string if the file has no extension. The result does not include the '.'.
    
    Since:
    
    11.0
  - getNameWithoutExtension
```
public static String getNameWithoutExtension(String file)
```
    Returns the file name without its file extension or path. This is similar to the basename unix command. The result does not include the '.'.
    
    Parameters:
    file - The name of the file to trim the extension from. This can be either a fully qualified file name (including a path) or just a file name.
    
    Returns:
    The file name without its path or extension.
    Since:
    
    14.0
  - fileTreeTraverser
```
public static TreeTraverser<File> fileTreeTraverser()
```
    Returns a TreeTraverser instance for File trees.
    Warning: File provides no support for symbolic links, and as such there is no way to ensure that a symbolic link to a directory is not followed when traversing the tree. In this case, iterables created by this traverser could contain files that are outside of the given directory or even be infinite if there is a symbolic link loop.
    
    Since:

  - isDirectory
```
public static Predicate<File> isDirectory()
```
    Returns a predicate that returns the result of File.isDirectory() on input files.
    
    Since:
    
    15.0
  - isFile
```
public static Predicate<File> isFile()
```
    Returns a predicate that returns the result of File.isFile() on input files.
