7-Zip creates ZIP compatible archives. 7-Zip supports the following ZIP compression methods:
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.
7-Zip supports LZH archives only for listing, browsing and decompressing. 7-Zip supports -lh0-, -lh4-, -lh5-, -lh6- and -lh7- methods.
