Sample code to convert from RAR to TAR.BZ2

Converting RAR archives to TAR.BZ2 format involves transitioning between two compression formats with distinct characteristics. RAR archives are known for their strong compression capabilities and widespread use. When converting them into TAR.BZ2 archives, which are commonly used in Unix-like systems, the original file structure and data are carefully preserved during the conversion process. This ensures that the content remains accessible and intact, making it suitable for specific use cases within Unix environments.

However, it’s important to consider that TAR.BZ2 archives may not offer the same level of compression efficiency as RAR archives. Therefore, users should weigh their requirements, including compression needs and compatibility with the target system, when deciding to perform this conversion. Converting RAR to TAR.BZ2 can be valuable for users who need to adapt RAR archives for specific Unix-based scenarios while maintaining data structure and integrity.

Code from RAR to various formats: The RAR archive typically contains multiple records or files. To convert this archive into formats such as GZ (Gzip), LZ (Lzip), Z (Unix Compress), XZ (XZ Utils), and BZ2 (Bzip2), a common approach is to first package the contents into a TAR.BZ2 (Tape Archive) format. This process is reminiscent of the typical practice in Linux environments.

In this conversion process, each file or record within the RAR archive is first bundled together into a single TAR.BZ2 archive. This TAR.BZ2 archive serves as a container for the individual files, preserving their original structure and metadata. Once the data is encapsulated within the TAR.BZ2 archive, it becomes easier to apply different compression algorithms and formats.

The choice of TAR.BZ2 as an intermediate format is due to its simplicity and wide compatibility across various Unix-like operating systems. It provides a straightforward way to group files together without applying compression directly. After the TAR.BZ2 packaging is complete, subsequent compression operations can be applied to the TAR.BZ2 archive to generate the desired output formats, such as GZ, LZ, Z, XZ, or BZ2.

Convert from RAR to TAR.BZ2 - C#:

    using (Bzip2Archive bzip2Archive = new Bzip2Archive())
        using (TarArchive tarArchive = new TarArchive())
            using (RarArchive rar = new RarArchive(@"archive.rar"))
                for (int i = 0; i < rar.Entries.Count; i++)
                    if (!rar.Entries[i].IsDirectory)
                        var ms = new MemoryStream();
                        ms.Seek(0, SeekOrigin.Begin);
                        tarArchive.CreateEntry(rar.Entries[i].Name, ms);
                        tarArchive.CreateEntry(rar.Entries[i].Name + "/", Stream.Null);
            bzip2Archive.Save ("output.tar.bz2");
