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 output 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.
- From Explorer you can rightclick on a file and
to split it from PeaZip's entry in SendTo or Context menu;
- Open PeaZip, chose "split file" or "join files"
main menu and provide the input file name (provide the .001 filename
for merging back split files).
- Add a file to the archive's layout; from
tab select "split" as format and set volume size and optional integrity
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.
If you prefer to use 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 (see documentation).
This is preferable also when handling multiple multimedia files in
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
go in "Advanced" tab when creating the archive and select no
compression (set compression to "store" level)
|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.
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
