7-Zip is a free files compressor available to download for reducing the size of files thanks to an efficient high compression algorithm.

With this software users can compress diverse and multiple files. Size can be reduced almost to the 50% of the initial volume. This is made possible through the use of “7z” format, obtaining compact results without losing quality. This software also works with any OS such as Windows XP and Windows 7.

This program is especially recommended when there is a need of freeing up your computer’s hard disk space. Besides, 7-Zip is compatible with many formats, such as XZ, BZIP2, GZIP, TAR and ZIP when it comes to compress/uncompress or encode/decode files.

A simple interface for reducing the files to "7z" format

7-Zip has a user-friendly and intuitive interface based on a double-panel files explorer. Also, main functions can be identified with colorful icons located at the top. This utility provides basic settings options to customize until it fits users’ needs.

Recovering zip files that have been corrupted or damaged is an arduous task. Repairing them turns to be essential if we want to read them again. Zip Repair Tool can do that for us just by clicking in the damaged files and repairing them in few seconds no matter their size.

If you want to try a different compressor with a different extension than 7z, Winzip is a good alternative, especially for novice users, as it provides a wizard guiding them in their first compressing experience. While 7-Zip is known for its high compression rate, Winzip stands out for its compression speed. Also, one of Winzip’s weaknesses is its low compatibility with other compression formats.

Conclusion

7-Zip allows users saving space and increasing their files' portability by its high ratio compressing capabilities and great formats support.

Pros
  • Platform is multilingual
  • Great compressing/uncompressing speed
  • Interface is intuitive
Cons
  • Old-fashioned interface

QUESTIONS AND ANSWERS

For what are you going to use the program?

7-zip is a powerful file archiver, that is used to compress large files into small zipped files

By Frank Kanyua

On Tuesday, January 20, 2015

7-zip is a powerful file archiver, that is used to compress large files into small zipped files. My My test to see the compression rate was with nfs most wanted which has about 2 Gb download memory and after compression it had 366 megabytes.

The compression rate is also very fast as it can top upto 300megabytes per second with a decompression rate of twice the amount. After compression the output only has one file and after decompression it can have many files and folders.

7-zip also offers password protection with the length as a minimum of 1 and a maximum of 17 characters. The longer the password the stronger it becomes and less to crack it becomes.

It also offers short cuts so that using 7-zip can be easier. 7-zip also supports many file formats and can also compress and mail if you have a mailing address and software set in your computer.

When you download a zipped file you can choose to open it as archive or extract it. Opening as archive can prove to be useless if the file to run needs administration permission. Once you extract the zipped file everything that was compressed will be decompressed to their original file and the total download memory will be made available.

Conclusion

7-zip is a very excelent tool to use since its the one in the market, its free of charge for both commercial and personal use. it is also available for educational purposes if one is experimention on new files to associate with 7-zip

Pros

  • it is 100% free of charge
  • It offers high compression and decompression rates
  • It can open files as archives without unzipping

Cons

  • no cons i have encountered
