• POSIX ustar
• GNU tar format (including GNU long filenames, long link names, and sparse files)
• Solaris 9 extended tar format (including ACLs)
• POSIX pax interchange format
• POSIX octet-oriented cpio
• SVR4 ASCII cpio
• Binary cpio (big-endian or little-endian)
• PWB binary cpio
• ISO9660 CD-ROM images (with optional Rockridge or Joliet extensions)
• ZIP archives (with uncompressed or "deflate" compressed entries, including support for encrypted Zip archives)
• ZIPX archives (with support for bzip2, ppmd8, lzma and xz compressed entries)
• GNU and BSD 'ar' archives
• 'mtree' format
• 7-Zip archives (including archives that use zstandard compression)
• Microsoft CAB format
• LHA and LZH archives
• RAR and RAR 5.0 archives (with some limitations due to RAR's proprietary status)

The library also detects and handles any of the following before evaluating the archive:

• uuencoded files
• files with RPM wrapper
• gzip compression
• bzip2 compression
• compress/LZW compression
• lzma, lzip, and xz compression
• lz4 compression
• lzop compression

The library can create archives in any of the following formats:

• POSIX ustar

• "restricted" pax format, which will create ustar archives except for
  entries that require pax extensions (for long filenames, ACLs, etc).
• Old GNU tar format
• Old V7 tar format
• POSIX octet-oriented cpio
• SVR4 "newc" cpio
• Binary cpio (little-endian)

• GNU and BSD 'ar' archives
• 'mtree' format
• ISO9660 format
• 7-Zip archives
• XAR archives

When creating archives, the result can be filtered with any of the following:

• uuencode
• gzip compression
• bzip2 compression
• compress/LZW compression
• lzma, lzip, and xz compression
• lz4 compression
• lzop compression
• zstandard compression
