最近有Java解压缩的需求，java.util.zip实在不好用，对中文支持也不行。所以选择了强大的TrueZIP，使用时遇到了一个问题，做个记录。
解压缩代码如下：
ArchiveDetector detector = new DefaultArchiveDetector(ArchiveDetector.ALL,
new Object[] { "zip", new CheckedZip32Driver("GBK") } );
File zipFile = new File("zipFile", detector);
File dst = new File("dst");
// 解压缩
zipFile.copyAllTo(dst);
代码十分简洁，注意这个File是
de.schlichtherle.io.File
不是
java.io.File
当处理完业务要删除这个Zip File时，问题出现了：
这个文件删不掉！！！
把自己的代码检查了好久，确认没问题后，开始从TrueZIP下手，发现它有特殊的地方的，是提示过的：
File file = new File(“archive.zip”); // de.schlichtherle.io.File!
Please do not do this instead:
de.schlichtherle.io.File file = new de.schlichtherle.io.File(“archive.zip”);
This is for the following reasons:
1.Accidentally using java.io.File and de.schlichtherle.io.File instances referring to the same path concurrently will result in erroneous behaviour and may even cause loss of data! Please refer to the section “Third Party Access” in the package Javadoc of de.schlichtherle.io for for full details and workarounds.
2.A de.schlichtherle.io.File subclasses java.io.File and thanks to polymorphism can be used everywhere a java.io.File could be used.
原来两个File不能交叉使用，搞清楚原因了，加这么一句代码搞定。
zipFile.deleteAll();
