Convert EMZ to ZIP in Java

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.

What is ZIP file format?

The ZIP file format holds significant recognition and finds widespread application in file sharing and data storage. Its ability to compress files into smaller sizes makes it highly efficient for transferring and archiving large files. With broad support across various operating systems, ZIP files offer enhanced compatibility compared to other archive formats. Simplifying file management, ZIP files store all files and data within a single archive, eliminating the need for additional files or folders.

The versatility of ZIP files becomes particularly valuable when sharing multiple files or folders simultaneously. By compressing an entire folder into a ZIP file, users can easily distribute several files to others, simplifying the sharing process. Additionally, ZIP files provide an added layer of security by allowing users to protect their data with a password. This security feature proves particularly beneficial when sensitive information is involved, ensuring that only authorized individuals can access the files.

The benefits of ZIP files extend beyond their compression and security capabilities. ZIP files offer convenience by allowing for easy extraction of individual files from the archive, avoiding the need to extract the entire contents. This flexibility saves time and simplifies the retrieval of specific files from a compressed archive. Furthermore, ZIP files support various compression algorithms, enabling users to choose the level of compression based on their specific requirements.

Another advantage of the ZIP format is its ability to preserve file metadata, such as timestamps and permissions. This ensures that the archived files retain their original properties, making ZIP files ideal for data backup and preservation purposes. Moreover, ZIP files can be segmented into multiple volumes, facilitating the storage and transfer of large archives across different media or network connections.
