Winzip 10.0

The list presented in this article will give you an idea of some additional WinZip features. Please make use of the Search feature in this knowledge base or browse the categories to find even more information. You are also welcome to click Ask a Question to send an e-mail message to Technical Support.
  • Easily unzip a Zip file with WinZip on Windows 7 or Windows Vista; just open the Zip file and use 1-Click Unzip.
  • Create your own filters or use built in ones for greater control over which files you will be zipping.
  • Faster zipping with multi-processor support in compression algorithms
  • A WinZip Gadget with both a Zip/Unzip side and a Zip & Email side
  • If you zip Microsoft Office files one at a time or receive Zip files with one Office file inside, WinZip can quickly Auto Open the one Office file as you open the Zip file.
  • WinZip is configured by default to use NTFS time stamps (vs. DOS time). This allows for greater time stamp granularity/accuracy, and the use of Greenwich Mean Time (GMT) helps when sharing Zip files outside of your local time zone. This is particularly useful with Zip data backups.
  • Even if you do not have an e-mail application, WinZip's built-in e-mail feature allows you to use Zip and E-Mail and other similar features (WinZip 15 or later).
  • In order to improve network security, your administrator may have a policy to block .zip extensions. When working with a reliable source, you can exchange Zip files after agreeing on a fictitious alternate extension (e.g., ".abc"). Then you can configure WinZip to use this as an alternate Zip file extension. This will increase the likelihood that you will be able to send and receive Zip files, and WinZip will open them just as it opens any .zip file.
  • If you need to email an existing Zip file, WinZip makes it easier with the Send options available directly in the Home tab.
  • With WinZip Pro, you can extend the benefit of Send features with the ability to send to a remote FTP server and/or burn directly to CD/DVD.
  • WinZip can display Zip file comments of up to 64,000 characters.
  • Support for Unicode filenames ensures that international characters are accurately displayed for filenames in a Zip file when the Zip file is shared between two computers having different code pages (the default set of text characters available for display). For Unicode support, the Zip file must be created and opened with a Zip file utility that supports the Unicode extensions to the Zip file format.
  • WinZip removes from the list of recently used files any files that no longer exist and were opened from the temporary or Internet files folders. This means that, for example, Zip files opened from your e-mail program no longer appear in your recently used file list after they have been deleted by the e-mail program.

Winrar 3.6


  • WinRAR is a powerful compression tool with many integrated additional functions to help you organize your compressed archives.
  • WinRAR puts you ahead of the crowd when it comes to compression. By consistently creating smaller archives, WinRAR is often faster than the competition. This will save you disc space, transmission costs AND valuable working time as well.
  • WinRAR supports all popular compression formats (RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z and 7-Zip).
  • WinRAR is ideal for multimedia files. WinRAR automatically recognizes and selects the best compression method. The special compression algorithm compresses multimedia files, executables and object libraries particularly well.
  • WinRAR allows you to split archives into separate volumes easily, making it possible to save them on several disks for example.
  • WinRAR is also ideal if you are sending data through the web. Its 128 bit password encryption and its authenticated signature technology will give you the peace of mind you have been looking for.
  • WinRAR is shareware, meaning you have the chance to thoroughly test it. The program can be used absolutely free of charge for 40 days!
  • WinRAR licenses are valid for all available language and platform versions. If you have purchased several licenses, you can even mix versions to meet your own personal needs.
  • WinRAR gives you all future UPDATES for FREE!, not like the competition that will make you pay again every one or two years.
