Luckily, NIO.2 > supports this. File creation for 4 GiB will be tens of milliseconds. Use this > snippet as soon as we move to Java 7: > {code:java} > Path tempDirectory = Files.createTempDirectory("jetty"); > final ByteBuffer buf = ByteBuffer.allocate(4).putInt(2); > buf.rewind(); > final OpenOption[] options = { StandardOpenOption.WRITE, > StandardOpenOption.CREATE_NEW , StandardOpenOption.SPARSE }; > final Path hugeFile = tempDirectory.resolve("hugefile.txt"); > try (final SeekableByteChannel channel = Files.newByteChannel(hugeFile, > options);) { > channel.position(HUGE_FILE_SIZE); > channel.write(buf); > } > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
