IOUtils is the most frequently used class. It provides operations to read, write, copy and close streams.
FileUtils provides operations based around the JDK File class. These include reading, writing, copying, comparing and deleting.
FilenameUtils provides utilities based on filenames. This utility class manipulates file names without using File objects. It aims to simplify the transition between Windows and Unix. Before using this class however, you should consider whether you should be using File objects.
FileSystemUtils allows access to the filing system in ways the JDK does not support. At present this allows you to get the free space on a drive.
EndianUtils swaps data between Big-Endian and Little-Endian formats.
