Create random password, use PeaZip password managerThe software also provides an utility to create random keyfiles and random passwords, sampling entropy from user's system, and an encrypted password manager to help safely handling multiple passwords, to be used in PeaZip or in other applications, websites and services - also, use of random passwords avoid risks of password-guessing by unauthorized users with dictionary attacks or social engineering. Securely delete data and sanitize supports after intended lifecycleAs good practice, to avoid data theft and unauthorized data access, never let leak on de-commissioned supports any leftover data after end of intended lifecycle of that information. PeaZip provides integrate secure delete utility to wipe files and folders which are intended to be premanently destoryed, while system's standard file deletion procedures simply de-references data in the filesystem letting the actual information intact on the support, where appropriate data recovery software can be used by an attacker to recover data intended to be erased. Same function also allows to sanitize entire partitions in order to clean free (logical) disk space from remanants of data previously removed by unsecure deletion procedures - standard disk formatting procedures, similarily to standard deletion functions, by default does not take care to securely delete actual data on physical support, favouring speed over security.
Verify
data
integrity to detect modification
|
|
|
While
filesystems and communication protocols implement error detection
and error correction algorithms, usually speed is the primary design
goal, menaning more computing intensive controls are generally not an
option. Detecting files corruption or forgery (purposely crafted modifications of data to exploit weakness of some simple error detection mechanisms) as soon as possible avoids to work on, or backup, inconsistent data, and prevent wasting disk space for storing unwanted, unreadable files. |
|
Safely share, synchronize, attach, and upload files
PeaZip helps safely sharing files with other people and synchronize data with other computers/devices/services, consolidating multiple composite input files in a single output archive file so data is more handy to manage for any purpose and with any method (as email, ftp or other protocols 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 data package.
Convert archives when needed
|
|
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. |
|
Span large files to meet maximum size rules
If a maximum allowed size is mandatory, in example when attaching a file to a mail, file spanning feature can (in a single pass) create multiple split email attachments (file spanned in multiple .001, .002, etc parts), each one smaller than the desired limit size.
Use shared paths and cloud storage from PeaZip file manager
PeaZip file manager / file explorer automatically detects local paths containing Dropbox, Google Drive, Microsoft OneDrive (formerly known as SkyDrive) shared files.
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, gadgets 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 Microsoft Windows, Linux / Google Android or ChromeOS, and Apple MacOSX / iOS.
PeaZip file explorer shows available shared directories in the navigation area (on the left) of file browser, so shared files are quickly accessible - and also in compression/conversion and extraction screens, to allow quick selecting sync folders as target for archiving and extraction tasks.
This is especially useful when sharing archive files with mobile or ultramobile devices and gadgets not able to run 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.
Scan archived files with antivirus
|
|
Archive file content can be scanned for virus / malware before starting actual extraction of the content, read more about in-archive malware scanning with PeaZip. |
