Deprecated ClassesClassDescriptionUse IOUtils. Will be removed in 3.0. Methods renamed to IOUtils.write() or IOUtils.copy(). Null handling behavior changed in IOUtils (null data does not throw NullPointerException).Apache Commons IO no longer uses this class. Instead, use
PathUtils.walk(java.nio.file.Path, org.apache.commons.io.file.PathFilter, int, boolean, java.nio.file.FileVisitOption...)orFiles.walkFileTree(java.nio.file.Path, java.util.Set, int, java.nio.file.FileVisitor), and friends.Use WildcardFileFilter. Deprecated as this class performs directory filtering which it shouldn't do, but that can't be removed due to compatibility.As of 2.6 deprecated without replacement. Use equivalent methods inFileStoreinstead,Files.getFileStore(Paths.get("/home")).getUsableSpace()or iterate overFileSystems.getDefault().getFileStores()UseBoundedInputStream(unbounded by default).
