1. There is a recent project requirements, that is, from the oos download and extract the compressed package, to decrypt the swf demand.
2. Unzip the process, to show the progress of decompression. After successfully decrypt the swf file decompression.
3. sinkhole on display unzip progress: there are eight of ten online method:

}1. This method has a big problem is that progress is not complete, unzip the successful determination has big loophole (when extracting files in the U disk, unplug the U disk decompression process will actually go decompression judging success !!! )
progressMonitor.getTotalWork() == progressMonitor.getWorkCompleted()2. no good solution yet
3. Only take the second decompression method but there are limitations (must be a multiple archive files)
