ZArchiver is a program designed for archive management. It features a simple and functional interface that allows users to create and decompress various archive types, including 7z, zip, bzip2, gzip, XZ, lz4, tar, and zst. The app does not have permission to access the internet, ensuring that no information is transmitted to other services or persons. Users can also view archive contents, create and decompress password-protected archives, and edit archives by adding or removing files. Additionally, ZArchiver supports multithreading and UTF-8/UTF-16 for filenames, allowing users to use national symbols in filenames.

ZArchiver is particularly useful for small files (<10MB) as it can start with Android 9 and use direct opening without extracting to a temporary folder. It also supports multithreading, which is beneficial for multicore processors. Users can send any useful ideas or wishes by email or leave a comment. The app also includes a mini FAQ that answers common questions, such as how to compress and extract files and what to do if the program is not working correctly.

To compress files using ZArchiver, users can select all the files they want to compress by clicking on icons from the left of filenames. They can then click on the first of selected files and choose "Compress" from the menu. After setting desired options, users can press the OK button. To extract files, users can click on the archive name and select suitable options, such as "Extract Here" or other. If users encounter any issues, they can send an email with a detailed description of the problem.

In summary, ZArchiver is a useful program for archive management that supports various archive types, password-protected archives, and multithreading. It also features a simple and functional interface and supports UTF-8/UTF-16 for filenames. Users can compress and extract files easily and send any useful ideas or wishes by email or comment.
