AnyZip has a unique feature that allows you to create an archive
file spanning across more than one disk or storage unit. This feature
is very helpful while creating an archive when the size of the files
to be compressed is larger than would fit on a single disk. Using
this feature makes it easy to create multi-disk archives without
your having to manually determine which files to include on one
disk. AnyZip addresses this requirement by limiting the size of
each archive to a user-defined size.
A multi-volume archive can either
be created based on a user-defined
size or using
AnyZip's auto-detect feature.
User-defined Multi-Volume archive
In the example below, we are attempting
to create an archive from a list of files. In addition to specifying
the name and location of the file, the we have specified in this
case using the Split to Volumes option that the size of the resultant
archive files should not exceed 500 KB.

user-defined file size
Based on these parameters, AnyZip
has created archive files as follows:

based on user-defined size
As the total size of the files selected
for adding to the archive is 2.99 MB, AnyZip has created an archive
consisting of five files of 500 KB each and a sixth one of 453 KB.
This makes it easier to now copy these files into a storage disk
such as a floppy disk.
Further, AnyZip has also marked the
files with a 00n extension, numbered from 000 to 004. This
is helpful while extracting files from floppies as AnyZip prompts
users to insert floppies into the disk drive after completing extraction
after reading each piece of the archive. The prompt that is displayed
contains the name of the file along with its extension. In order
to carry out the extraction the user has to select the main archive
file i.e. the file titled Media.Zip in the above list.
Auto-Detect based on disk drive
When you select the Auto-Detect option
for creating a multi-volume archive, AnyZip detects the right size
of the archive based on the disk drive in your computer. In case
you have a floppy disk drive which takes only 1.44 MB floppies AnyZip
will create an archive in such a way that the size of each component
of the archive file is no more than 1.44 MB in size. In order to
use this feature, select the Auto-Detect option while creating an
archive as shown below:

to Volumes field
AnyZip will create the archive based
on the capacity of your disk drive in the same manner as described
in the earlier section. The same rules also apply for extracting
files from within such an archive.
