ZIP

7-Zip creates ZIP compatible archives. 7-Zip supports the following ZIP compression methods:

• 0 - Store
• 1 - Shrink (decompression only)
• 6 - Implode (decompression only)
• 8 - Deflate
• 9 - Deflate64
• 12 - BZip2
• 14 - LZMA
• 95 - xz (decompression only)
• 98 - PPMd
• 99 - WinZip AES

Files compressed with other ZIP compression methods can't be extracted by the current version of the 7-Zip. But these supported methods are the most popular today, and therefore 7-Zip can decompress most ZIP archives. To extract files compressed with non-supported methods you must use some other ZIP utility.

7-Zip supports the Zip64 extension of ZIP format.

LZH

7-Zip supports LZH archives only for listing, browsing and decompressing. 7-Zip supports -lh0-, -lh4-, -lh5-, -lh6- and -lh7- methods.
