> FILE SHARING
Share, attach or
is a file archiver utility, its point being consolidating
composite files in a single archive file so it is more handy to manage
for any purpose, including saving, copying and sharing the file, with
any method as email, ftp or other protocol such as torrents or p2p.
Moreover, supporting high compression algorithms, output file is
usually significantly smaller than the sum of sizes of input files,
saving bandwidth and time both for uploading and downloading the file.
If a maximum size is mandatory, in example when attaching a file to a
mail, file spanning feature can (in a single pass) create multiple
split output file parts (.001, .002, etc), each one smaller than the
The integrated archive conversion function ensure the ability to change
the type of an existing archive, extracting and effectively
re-compressing its content in the desired file format, in order to, in
example, transform old archives (as backup files) into a more up to
date format either for improved compression or better security, or to
be able to share data with users being able to read only a subset of
the archive formats supported by this software.
PeaZip also features strong encryption protocols (AES for 7Z and ZIP;
AES, Twofish and Serpent for PEA and ARC files), including encryption
of table of content of the archive, in order to keep the content of the
file private. Two factor authentication is optionally supported, to
improve the security of password based protection, and an encrypted
password manager is also featured to help safely storing multiple
Hint: to directly email an
archive compressed with PeaZip you can either
- select desired files, riightclick and use PeaZip >
Zip and mail system context menu entry
- use Send by mail option in archive creation interface
Share and synchronize data
with PCs and other devices (tablet, smartphones)
PeaZip automatically detects local paths for mainstream cloud storage
Cloud based synchronization platforms allows users to store data on a
remote location that is mutually accessible by different devices owned
by the user, like multiple PCs, smartphones, tablets/phablets etc,
basically any device capable to connect to Internet and run the file
synchronization software, which for this reason is usually
multi-platform and can run on Windows, Linux and Android, and Apple
MacOSX and iOS.

PeaZip shows available shared directories in the navigation area (on
the left of file browser), so shared files are quickly accessible.
Moreover, file compression/conversion and archive extraction interfaces
shows shared directories in the dropdown directory selection menu, for
quickly selecting sync folders as target for archiving and extraction
This is especially useful when sharing archive files with mobile or
ultramobile devices not
running a full featured file archiver (i.e. because some archive
formats or encryption protocols are not supported, or because not
enough powerful for convenient use of strongest compression algorithms,
especially on very large archives, or because no viable freeware
choices are available, or because locked for some policies), but fully
capable to handle the content of the
archive once it is extracted.
Receive or download
PeaZip support extraction of over 180 archive types, including most
popular file formats used on file sharing platforms like RAR, ZIP, ZIPX
and TAR files, support decryption of password protected files and
joining split set of files (.001, .z01, .r01 files).
Many checksum and hash algorithms are supported by this application in
order to detect file
corruption or forgery; same algorithms can also be used to de-duplicate
order to check for duplicate content in order to reduce disk space
waste and make file collections more manageable.
Finally, secure deletion can take care of permanently remove unwanted
files from disk making unfeasible recovery of the unwanted files.
