Splitting a file
in PeaZip you can
select the volume size form a series of pre-set sizes (floppy disk,
attachment maximum size, CD,
DVD...) or you can customize it up to byte
split is recommended every time it is needed to fit data in
a mandatory output
size (such as maximum email
attachment limit or media support size), rather than
proceding with trial and error compression attempts hoping to reduce
the file size under that limit, which may not be possible even with
best compression and higher settings.
message / media will contain up to the specified amout of data,
guaranteeing the package can be sent / written to disk without errors.
different, alternative ways to split/join files:
If you are
file into multiple removable media, PeaZip will check if the media
has enough free space for storing the volumes, and will be asked you to
provide a new empty media each time the previous one is full.
- Add files and folders to the archive's layout (i.e.
select it and click Add
- Click volume size dropdown menu (by default set on
"Single volume, do not split") in order to split the output to multiple
volumes, chosing from custom or pre-set sizes (recommended email
attachment sizes, CD, DVD, etc): this method allows to combine the
benefits of archiving (consolidating multile input files & folders
into a single output stream), compression (reducing disk occupation
eliminating data redundancy), and file spanning (keeping the output in
volumes smaller than a given maximum size).
- Alternatively, change archive type option (below
output path option) to
"Split" and set volume size and optional integrity
- Open PeaZip, chose File manage > File Tools >
"split file" or "join files"
main menu and provide the input file name (provide the first volume of
the set, usually the file with .001 extension
for merging back spanned archives).
- From Windoiws file explorer you can rightclick on a
to split it from PeaZip's entry in SendTo or Context menu;
Purely splitting a file does not
involve compression, that is usually only
marginally efficient on multimedia files, like ie. MP3, OGG and other
audio formats, or AVI, MPEG, DIVX and other video formats.
As said before, if you prefer to combine splitting with compression,
you can add the file(s) to a ZIP or
7Z archive and chose to split (cut) the archive in volumes of a fixed
in order to keep them below the size limits of a support or mail
attachment: this is preferable also when handling multiple multimedia
order to store them in a single archive, split in fixed sized volumes,
rather than having to split each file separately.
In this case you can set minimum compression or no
compression ("store" level) to speed up the process avoiding to
compress scarcely compressible data: hints how to improve file
compression, how to
reduce size of images
|When you receive a
multipart file or archive, to join the data
back to obtain the original file, move
or copy all the parts of the file in the same
folder before proceeding with extraction
|Open the first archive's part with
PeaZip, i.e. doubleclick on the
first volume wich is usually identified with extension .001, .Z01, R01,
.PART1 or similar - please some times set counter stars from 000, R00,
Now you can extract it wit
"Extract" or "Extract all" from
PeaZip's toolbar or context menu, or just drag content from PeaZip to
righclick on the first volume of the spanned file and
use "Extract" or "Extract
here" PeaZip's entries in system's context menu
