- Added ZIP compression by default
- Using Apache Commons Compress library to enable ZIP compression
- Added benefit is that zip files store the filename by default. If we lose the index file it will still be possible to reconstruct the names for each file, albeit at this moment the path information would be lost
- On a source project of 5Mb, a compressed file is 1Mb. With the overhead of our implementation results in 1.5Mb and this is still a very impressive reduction on disk space
- Adding files to a big archive is now considerably slower due to the compression taking place
