Share, attach or
upload files
PeaZip
is a file manager and archiver utility, its point being
consolidating
multiple
composite files in a single archive file so it is more handy to manage
for any purpose, including saving, copying and sharing or sending the
file, with
any method as email
attachment, ftp upload or
other protocol such as torrents or
p2p sharing, or cloud services.
Lern more how to create
file archives, and how to zip each file in
a separate archive.
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 large
files: read more about how to use archival formats providing best
compression ratio: how to create 7z
files, how to create
Zpaq files.
Please remember that the recipient need to be able to open the archive of
chosen format, so whenever unsure of the software available to the
recipient it is adviceable to create
Zip files (on Windows), or create Tar
files (on Linux / macOS), because the ubiquitous support.

If a maximum file size
limitation is
mandatory, in example when attaching a large file to an
email or uploading to a web storage service, file
spanning feature
can (in a single pass) create multiple
split output file parts (.001, .002, etc), each one smaller than the
desired size - compatible with Unix / Linux split command, and
applications like HJSplit, and 7-Zip - to avoid risk of the payload
being rejected by the service for exceeding maximum allowed size. |
The integrated archive files 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
- the sender needs to share data with recipient users
being able to read only a subset of
the archive formats supported by sender's software
- the sender needs to avoid the attachment being
rejected by some
services due security risk concerns frequently associated with some
specific formats - i.e. Gmail and some email services rejecting
encrypted zip files, being commonly used as vectors for virus, password
protection effectively preventing in-archive
malware scanning.
PeaZip also features strong file
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 (encrypt
the list of archived files and folders), in order to keep the
content of the
file private applying end to end encryption before sending data or use
any cloud / upload service. 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
passwords.
Hint: to directly attach
to email an
archive compressed with PeaZip you can either
- select desired files, rightclick, and send them with
"PeaZip" >
"Zip and mail" system context menu entry
- alternatively, use "Send by mail" option in archive
creation interface of PeaZip
in both cases remember to
check maximum attachment size, and use file spanning (splitting)
function if output archive is larger than allowed size
Cloud,
synchronize data
with PCs and other devices (tablet, smartphones)
PeaZip file manager

Cloud based
synchronization platforms allows users to store data on a
remote network 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 the 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
macOS and iOS.

As
additional endpoint privacy measure, PeaZip can encrypt files
getting shared or stored on cloud services. |
|
PeaZip file manager shows available shared cloud 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
tasks.
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 in uncompressed form.
Securely receive or
download
files
PeaZip support
extraction of over 200 archive types, including most
popular file formats used on the Internet and 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).
|
The
application can scan for
malware and virus inside received or downloaded archive files before
proceding with extraction
- last group of entries in PeaZip's "Test" context menu shows available
antimalware / antivirus software that can be used to scan open archive,
or scan multiple selected archive files before opening them in PeaZip,
in this case if the security software supports reading that format.

Many checksum and hash
algorithms (CRC32, CRC64, MD5, SHA, SHA2, SHA3...) are supported by
this application for file
integrity test against known in
order to detect file
corruption or forgery in downloaded (or received) data, to avoid risks
inherent in opening / storing
corrupted, non
verified files coming from the web or any untrusted remote source.
Confronting hash values can also help to find (and remove) duplicate files
to save disk space.
Unreadable files can
also be tested trying to open them providing a
password, in case they are in fact encrypted files with changed
extensions.
Same algorithms can
also be used to de-duplicate
files, searching for duplicate content in order to reduce disk space
waste and make file collections more manageable after duplicate files
gest removed.
Finally, secure deletion can take
care of permanently remove unwanted
files from disk making unfeasible recovery of the unwanted (or
unreadable) files.
