How to split and join files with PeaZip?
command,
HJSplit, 7-Zip...optionally PeaZip can save a separate control file containing checksum or hash of each volume and of the complete original file, allowing file level and volume level integrity check, which will be ignored by other file split utilities, allowing to keep full compatibility with them.
Split a file in smaller parts
Splitting a file you can select the volume size form a series of pre-set sizes (floppy disk, typical mail attachment, CD, DVD...) or you can customize it up to byte level.- From Explorer you can rightclick on a file and
chose
to split it from PeaZip's entry in SendTo or Context menu;
- Open PeaZip, chose "split file" or "join files"
from
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 "Options" tab select "split" as format and set volume size and optional integrity check algorithm.
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 the archive in volumes of a fixed size, 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)

Joining file parts
When you receive a
multipart file or archive, to join the original file
back:
- place all the parts of the file in the same folder
- open it with PeaZip, i.e. doubleclick on the first volume, usually identified with extension .001, .Z01, R01, .PART1 and similar
- extract it wit "Extract" or "Extract all" from PeaZip's toolbar or context menu, or just drag content from PeaZip to the system
