The most commonly used classes are described here: 23</p> 24<p> 25<b>IOUtils</b> is the most frequently used class. 26It provides operations to read, write, copy and close streams. 27</p> 28<p> 29<b>FileUtils</b> provides operations based around the JDK File class. 30These include reading, writing, copying, comparing and deleting. 31</p> 32<p> 33<b>FilenameUtils</b> provides utilities based on filenames. 34This utility class manipulates filenames without using File objects. 35It aims to simplify the transition between Windows and Unix. 36Before using this class however, you should consider whether you should 37be using File objects. 38</p> 39<p> 40<b>FileSystemUtils</b> allows access to the filing system in ways the JDK 41does not support. At present this allows you to get the free space on a drive. 42</p> 43<p> 44<b>EndianUtils</b> swaps data between Big-Endian and Little-Endian formats. 45</p> 46</body> 47</html> 48
