-ms[list]
Specify file types to store.

Specify file types, which will be stored without compression.
This switch may be used to store already compressed files,
which helps to increase archiving speed without noticeable
loss in the compression ratio.

Optional <list> parameter defines the list of file extensions
separated by semicolons. For example, -msrar;zip;jpg will
force RAR to store without compression all RAR and ZIP
archives and JPG images. It is also allowed to specify wildcard
file masks in the list, so -ms*.rar;*.zip;*.jpg will work too.

If <list> is not specified, -ms switch will use the default
set of extensions, which includes the following file types:

ace, arj, bz2, cab, gz, jpeg, jpg, lha, lzh, mp3,
rar, zip, taz, tgz, z
