Convert TAR Files to EMZ in Java

What is TAR file format?

A TAR (tape archive) file serves as a versatile archive format, primarily utilized on Unix and Linux systems, housing multiple files alongside their associated metadata. This metadata comprises essential information like filenames, permissions, ownership details, file sizes, and other file system requirements. TAR files have gained widespread adoption as a means of storing and transferring files, particularly over the internet.

Creating a TAR file involves amalgamating multiple files into a single archive and subsequently compressing it using compression programs like gzip or bzip2. This compression process significantly reduces the file size, facilitating easier storage and transfer. Extracting files from a TAR archive is accomplished using the TAR program, enabling the recreation of the original files.

TAR files have become a fundamental part of the Linux and Unix ecosystem and are also supported by other operating systems that recognize the TAR format. Their usage extends beyond file management, as software developers frequently employ TAR files to package and distribute their software applications. By bundling all the necessary files and metadata, TAR files streamline the distribution process, ensuring that all components are packaged together for easy installation.

Moreover, TAR files find their place in the realm of data backup. Backup software often employs TAR files to store system backups, capturing all relevant files and metadata required to restore a system to a previous state. The TAR format provides a reliable and efficient method for creating comprehensive backups, safeguarding critical data against loss or corruption.

What is EMZ file format?

The EMZ file format is a bitmap image format associated with Microsoft Windows. It is an enhanced version of the Windows Metafile (WMF) format and includes the same vector and raster imagery as WMF files, with the addition of compression and additional image information. EMZ files are often used by Microsoft applications such as Word and PowerPoint to store vector images. EMZ files can be opened using many image viewers, including Microsoft Office and Adobe Illustrator, as well as popular image editing programs such as Adobe Photoshop. As with other image formats, EMZ files support various color depths and file sizes, allowing for relatively small images, as well as high-resolution images with millions of colors. Although EMZ files are generally smaller than WMF, their compression does not necessarily lead to a good quality image. As with any compressed format, the quality of the image depends on the degree of compression used, so it is important to use the appropriate settings when compressing an EMZ file. In general, EMZ files are best used for graphic images that do not need to be modified, such as logos and other types of corporate artwork. They are also suitable for use in presentations where the quality of the image is not critical.
