WinBZip2

Some files could use a size trimming, in order to fit certain limits, such as image disc limitations or email file size. This can be easily achieved using archivers and size compressors, that can significantly reduce the maximum size of any chosen file.
WinBZip2 is a reliable software solution to compressing certain files generated by the bzip2 application. This utility comes as a handy interface to the bzip2 command line program. It allows you to further decrease the size and increase the compression ration of various bzip2 files. The application is standalone, thus it does not require any installation, and it can be ran from most storage units.
Furthermore, you can even create such archives, by simply selecting a file and compressing it. You can choose the work factor and memory blocks used for compression. Besides compression and decompression, you can use WinBZip2 to analyze the integrity and consistency of any bzip2 file.
You can significantly reduce the size of certain files, by selecting a high work factor and maximum memory blocks usage, then compressing the desired file or bzip2 archive. This way, you can ensure the lowest size for your archives, whilst maintaining file integrity and consistency.
Although it can compress files at a high rate, the application is not a full-on archiving utility, since it does not support batch compression. You can only use it to archive one file. Reusing advanced algorithms, such as the Huffman coding and the Burrows-Wheeler block-sorting text compression algorithm, WinBZip2 can seamlessly reduce the size of your files.
You can use this utility effectively in order to send and receive large files via email. Simply compress a large file that would normally exceed the size limit of an email, attach itl, then use the same application to decompress it after downloading the archive.System requirementsAbout 0.6 Megabytes of free space on hard disk
