Zip-Ada v.47 with LZMA decompression

The title tells everything - doesn't it ?...
Downloads and informations: here .

The LZMA format is especially good - understand: with a smaller compressed size than the good old Deflate format, even when data is compressed by refined and extensive algorithms - for large data (say 64KB or more), and is really amazing for structured data like CSV files or database files.

Of course the ReZip tool includes now LZMA as well and finds for each entry in a Zip file the smallest compression, be it LZMA or the other supported formats.

Here are a few graphics with compressed-to-original size ratios of the same data zipped under different names and with different archiver programs and different compression formats in a single zip archive file.
