What can I use PowerZip for?

  • Unzip Internet Downloads
    If you download files from the Internet, you have undoubtedly came across Zip files. Documents, pictures, themes, wallpapers, programs are all commonly distributed as Zip files to reduce the download time. When you download PowerZip, you will be able to access these files quickly and easily. Of course, Zip files are not the only type of compressed files supported by PowerZip. PowerZip also has built-in support for Cab, Rar, Tar, Gz, Bz2, Z, Ace and Jar files so you'll never run into a file which PowerZip cannot handle.
  • Unzip E-mail Attachments
    When files and documents are sent via e-mail, they are often placed inside a Zip file to reduce the number and the size of the attachments. You can use PowerZip to open these Zip attachments. Of course, PowerZip will unzip any Zip file, it doesn't have to be an attachment.
  • Communicate more effectively
    If you send files or documents by e-mail, you will benefit from using PowerZip to package them in a Zip file; you can then send the Zip file as an attachment. Compression will reduce the size of the attachment, so the e-mail will take less time to send and to receive. You can also password-protect the Zip file for privacy. You can Zip & E-mail files with a single click. Your e-mail recipient will be able to use any Zip program § to unzip it.
  • Encrypt / password-protect files
    You can use PowerZip 7.0 to create encrypted (password-protected) Zip files in order to prevent unauthorized access to confidential documents. You can use password-protected Zip files to store private documents and files or to send them through insecure channels such as e-mail. PowerZip can also unzip password-protected archives created by other programs. You have the option of either using the standard Zip encryption or, for extra protection, using 256-bit AES § which offers a high level of data security. To quickly encrypt a file, just right-click on it (in Windows Explorer / My Computer) and select "Encrypt".
  • Create & maintain backup
    Everyone knows how important it is to regularly backup important files and documents. Unfortunately, all too often backups are either not done or are not kept up to date. PowerZip makes it easier to create & maintain backups. You can use PowerZip to zip the files and folders you wish to backup into a single compressed archive. Not only is the single archive easier to handle but it is also smaller than the original files. And if you are storing the backup on floppy disks, PowerZip can split it across multiple disks if necessary.
    PowerZip also allows you to create PowerZip Macro Files. A PowerZip Macro File stores all compression settings in a file so that a compression (or extraction) operation can be re-played later. This means that you can select the files / folders you wish to store in the backup once and then compress the same files / folders again later (to make a new backup) with a simple double-click.
    Restoring the backup is equally easy. You can just right-click on your Zip file and choose Unzip or double-click on it to open the archive in PowerZip. Doing the latter will allow you to selectively view and unzip individual files in the archive.
  • Store away infrequently used files
    Do you have large files sitting on your hard drive that you need to keep but only use infrequently? You can use PowerZip to compress these files, saving valuable disk space. And when you need to access the files again, you can unzip them with PowerZip in seconds. If the files you are compressing are of confidential nature, you can also choose to password-protect the Zip file when compressing the files.
  • Automate compression tasks
    You can quickly create PowerZip Macro Files to automate common compression tasks such as routine backup. A PowerZip Macro File stores all compression settings in a file so that a compression (or extraction) operation can be re-played later with a single double-click. PowerZip Macro Files can also be executed as part of an automatic script such as a BAT file.
  • Create self-extracting archives
    A self-extracting archive is an executable program file (i.e. an EXE file) that includes both an archive and the software to unzip it. Users can extract the contents of a self-extracting archive by simply double-clicking on it. This is convenient when sending files to other people, because the recipient won't need a compression program (like PowerZip) to unzip your files. You can use PowerZip to create flexible self-extracting archives to suit your needs. You are able to include a start-up message, specify a command to be executed after extraction, specify the default extraction folder and select from several other options.
