## ZIP

7-Zip creates fully ZIP compatible archives. Anyone can decompress these files by any ZIP compatible decompression utility. During compression 7-Zip can use one of the following ZIP compression methods:

- 0 - Store
- 8 - Deflate
- 9 - Deflate64
- 12 - BZip2

The current version of the 7-Zip can extract any files from ZIP archive that were compressed with one of the following methods:

- 0 - Store
- 1 - Shrink
- 6 - Implode
- 8 - Deflate
- 9 - Deflate64
- 12 - BZip2

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.

The current version of 7-Zip doesn't support Zip multivolume archives.

## LZH

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