The main purpose of this utility is to recompress and test
21
the zip archives to get the smallest possible size.
23
For recompression the 7-Zip (www.7-zip.com) Deflate
24
implementation is used. This implementation generally
25
gives 5-10% more compression than the zLib Deflate
28
For experimental purpose also the 7-Zip LZMA algorithm is
29
available with the -N option. In this case, the generated
30
zips WILL NOT BE USABLE by any other program. To make
31
them usable you need to recompress them without the -N
32
option. Generally this algorithm gives 10-20% more
33
compression than the 7-Zip Deflate implementation.

Recompress the specified archives. If the -1, -2,
65
-3 options are specified, it's used the smallest file
66
choice from: the previous compressed data, the new
67
compression and the uncompressed format. If the -0
68
option is specified the archive is always rewritten
69
without any compression.

Be pedantic on the zip tests. If this flag is
94
enabled some more extensive tests on the zip
95
integrity are done. These tests are generally not
96
done by other zip utilities.

Disable the compression. The file is
104
only stored and not compressed. This option is
105
very useful to expand the archives of .png and .mp3
106
files. These files are already compressed, trying to
107
compress them another time is really a waste of time
