Whether you're looking to save space, secure data, or just back up your important data in an efficient manner, 7-Zip has all the bases covered.
7-Zip is free, fast and tiny. As well as the all-important Zip format, there's support for the creation of numerous other types of compressed file including 7z, BZIP2 and TAR.
Things are even more impressive when it comes to 7-Zip's decompression support; the list is seriously lengthy: AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR and Z.
The fact that ZIP and RAR files are covered is reason enough to install 7-Zip right away – everything else is a bonus. Compression rates in the program's native format are particularly impressive.
If you need to be able to work with anything other than regular zip files, 7-Zip is ideal for the job. A tool that easily falls under the heading 'essential'.
