7-Zip Portable - File Archiver
7-Zip Portable version for Windows is an open source and free software file archiver designed and released by Igor Pavlov. The program focus mainly on users to compress executable or larger sized files this to facilitate the quick transfer of data from one computer to another. The program can also be used as a decompressor for data from digital photographs. The decompression function allows the user to combine multiple files in a single zipped file, which can then be transferred to any other computer with the aid of a Zip drive or other compatible storage media.
Similar to many other similar programs, 7-Zip is a free software that has been available to the public for sometime now. Although the original release was for Linux only, the portable edition is available for both Windows and MacOS X. While the software comes with an open-source archiving utility called 7-Zip Compresser, which is based on the OpenOffice suite of office applications, other features such as sharing and collaboration features remain under wraps. However, the portable version does allow the user to compress files with a thumb-sized format, which is compatible with Windows Zip disks.
While there are a number of other file archiving utilities for Windows, it is believed that the 7-Zip Portable version stands out due to the high compression ratio it achieves. Many programs cannot achieve a high compression ratio like the 7-Zip Portable does, which makes this new version's popularity even more astounding. The developers of the program suggest that even professional users can achieve a compression ratio of around 95%. This high compression rate makes it possible for the file to be stored in just a few seconds without the need of a backup system. In addition to this, the 7-Zip Portable is also available in several languages including English, Spanish, Korean, and Italian.
