DVD Span is a backup tool for writing the contents of large
folders across multiple discs. DVD Span can automatically determine the best organization
of each disk in order to fit the maximum amount of data on the minimum number of
discs. DVD Span is a great tool for backing up your music collection, photos, or
even your entire hard disk. And because it produces regular DVDs (or CDs/BluRay), no
special software is required to read or restore your backups. W
The following picture should be enough to explain how to use the
program, so long as you use the recommended defaults: burn with DVDSpan,
and use the UDF disk format.
To install, copy files into the folder of your choice (such as C:\Program
Files\DVDspan). InfraRecorder comes pre-installed with DVDSpan so no other
downloads are required. To un-install just delete the folder.
Step by step instructions & options

Order splits the files and folders between disks, in the order that you
dragged them into the source list. If a folder is too big to fit on a
disk, DVDSpan will write as much of it as possible to the disk, and then write
the rest of that folder to the next disk. This is the simplest disk layout
to restore from, but also the least efficient.
but keep top-level is the next most efficient option. It will find the
best way to organize the top-level folders in the source list across
disks, but will not split up the contents of those folders between
disks (Note: top-level refers to the individual folders you dragged to the source
list). This works great so long as none of your folders are too big to fit on one
Re-order to fit the most files is the most efficient
option; the order that each file is written to each disk is optimized to fit as
much as possible on each disk. In order to restore a single folder using
this organization, however, you will have to check each burned disk for
files from that folder.

The behavior of these buttons can be modified by the following options:
Burn disk with:
 DVDSpan Will write the disk using the built-in disk burning
engine (dashr) which uses Window's IMAPI2 libraries (automatically
included in all post-XP versions of Windows). This is fast, efficient,
and works great with UDF formatted disks (see below).
 InfraRecorder DVD Span will create IRP files,
which are small, and therefore fast to create. This is also a good option if you wish to re-organize some of the files
on the disk before burning it. The only downside is that InfraRecorder
cannot produce ISO 1999 format disks (see below). InfraRecorder
comes pre-installed with DVD Span.
 default for .ISO, then the output format is an
.ISO file. These are read by pretty much any
DVD/CD burring program. This allows you to use
your favorite DVD burning application, but also requires the most disk space and doesn't allow you to modify the disk layout. Note
that this option is not compatible with UDF format disks (see
Disk Format - There are 3 options for disk
formats, which influence what file-name lengths are supported on the

however). Note: You can only burn this format using DVDSpan or InfraRecorder.

OSes, with no extra software needed. But, filenames are limited to 103
 ISO 1999 - this format supports 255 character
long file names, and works well with Windows, but the MacOS has difficulty reading these disks.
Neither InfraRecorder nor DVDSpan can output this format, so you can only make
this kind of disk if you select "default for .ISO" as
your burning software.

want to leave this checked. When checked, DVD Span will immediately
launch the appropriate program to burn the intermediate output file, and
then delete the intermediate file after burning completes.

it is on a disk with sufficient space, especially if you use the "default
for .ISO" option.
Restoring files from backup
Restoring from a backup is simple and does not require DVD Span
to be installed. All files are written to the disks with their subdirectory
structure preserved. Just put each disk in your drive one by one, and copy
each top level folder back to its original location using Windows Explorer. In
the event that the folders have been split between disks, Explorer will ask you
that you want to "overwrite folders". To properly restore, answer yes to this prompt.
2.10: Revised disk space calculation, better integration with
2.00: Support for BluRay disks via our own DVD/Blu/CDR burning
1.20: Drag and Drop fully supported in Windows 7 when running as
administrator or a regular user. Windows theme support added. InfraRecorder 0.53
1.09: Now include DLLs that some users needed to make .ISO
1.08: Support for >4GB files. Includes InfraRecorder
1.07: Improved error messages and error checking. Now uses
InfraRecorder 0.5, which has much improved compatibility.
1.06: More verbose error messages. Temporary directories can
have spaces in their names.
1.05: Empty directories are now backed up; DVD-Dual
Layer disks are now supported.
1.04: Unicode support for use with InfraRecorder (note
ISO files do not support Unicode); improved disk usage calculations which take
into account per-file overhead.
