ZArchiver - is a program for archive management. It has a simple and functional interface. The app doesn't have permission to access the internet so cannot transmit any information to other services or persons.

ZArchiver lets you:

- Create the following archive types: 7z (7zip) zip bzip2 (bz2) gzip (gz) XZ lz4 tar zst (zstd);
- Decompress the following archive types: 7z (7zip) zip rar rar5 bzip2 gzip XZ iso tar arj cab lzh lha lzma xar tgz tbz Z deb rpm zipx mtz chm dmg cpio cramfs img (fat ntfs ubf) wim ecm lzip zst (zstd) egg alz;
- View archive contents: 7z (7zip) zip rar rar5 bzip2 gzip XZ iso tar arj cab lzh lha lzma xar tgz tbz Z deb rpm zipx mtz chm dmg cpio cramfs img (fat ntfs ubf) wim ecm lzip zst (zstd) egg alz;
- Create and decompress password-protected archives;
- Edit archives: add/remove files to/from the archive (zip 7zip tar apk mtz);
- Create and decompress multi-part archives: 7z rar(decompress only);
- Partial archive decompression;
- Open compressed files;
- Open an archive file from mail applications;
- Extract split archives: 7z zip and rar (7z.001 zip.001 part1.rar z01);

Particular properties:
- Start with Android 9 for small files (<10MB). If possible use direct opening without extracting to a temporary folder;
- Multithreading support (useful for multicore processors);
- UTF-8/UTF-16 support for filenames allows you to use national symbols in filenames.
