What are mult-part
Multi-part archives are, typically, .7z, .rar, .zip files spanned on multiple volumes, each volume
containing part of the data split in order to be conatined in a size
below the desired maximum size.
This spanning process allows the archive to:
PeaZip supports both creating spanned multipart archives, and opening
and extracting multipart archives from different archive manager
utilities in multiple formats.
- be sent through channels enforcing a maximum payload
size, e.g. maximum attachment size for some email providers, or maximum
allowed file size for upload or cloud services
- be saved on filesystems where maximum file size
limitations are still relevant, i.e. FAT filesystems
The first volume, the one
named with the lowest progressive number (usuallay starting from 1,
seldom from 0) it is the part that
needs to be opened or extracted in order to access the full
content of the archive.
Most commonly multivolume archives are found with .001 extension (usually 7Z or ZIP
files spannd by 7-Zip, PeaZip and similar apps), .part01.rar or .r01 (usually multi part RAR files
created by WinRar), or .z01
(usually multi part ZIP or ZIPX archives created by WinZip).
How to open multi-part
From the system file explorer, or from PeaZip file manager double click (or right click > Open as
archive) the first volume of
the multi part archive.
In order to be able to list the entire archive content it is
recommended to save all the parts of
the spanned archive in the same folder.
The first volume of the archive is the one with the lowest progressive
number, and it can be usually identified as .001, .r01, .z01, or .part01.rar,
and other parts should show the same filename and extension type with
progressively increasing numbering.
Once all archive parts are in the same directory, open the first part
with PeaZip to be able to browse,
search, list, test or extract the entire multi-part archive.
How to extract
(or copy) all the parts of the multi-volume archive in the same
folder before proceeding with extraction.
The spanned archies are usually 7Z, RAR or ZIP archives split in
multiple smaller parts (volumes).
The parts have same name, same extension type, and shows progressive
numberting: no part should be missing or else some of the original
content will not be available for extarction
first volume (part) of the smanned archive as explained in the
previous section "How to open multi-part archives", or esle proceed to directly extract the
first volume of the archive using one of the following available
The first volume of the archive can be identified by the extension
which is usually .001, .r01, .z01, .part01.rar.
- From the system file manager, righclick on the
first volume of the multi part archive and use "Extract" or "Extract
here" PeaZip's entry in system's context menu.
- From PeaZip file manager, select the first
volume of the spanned archive and click Extract button, or use app's
context menu Extract entry
If a password is required to
extract an encrypted multi-part archive, it can be set from the
locker icon in the extraction screen in PeaZip before confirming
extraction with the OK button on the bottom of the application.
