File extension	.rar
Category	Archive File
Description	Named after its Russian creator, the RAR format, standing for Roshal Archive, is a compressed file type. The compression technique used to create RAR files is proprietary and has been licensed to other paid and freeware compression file applications. The RAR format also provides features such as repair, which will attempt to restore part or all of the file when physical damage has occurred. The RAR format established itself as a rival to the ZIP file format due to its superior compression ratios.

Technical Details	The RAR format allows for an extremely large potential file size, with 20 Exabyte's being the upper limit. The format permits spanning across multiple RAR files. This sometimes leads to the file extension being renamed from .RAR to .R01,.R02 etc. This is particularly useful when an archive needs to be transferred to removable media such as a memory card or CD/DVD. RAR, along with several other lossless file compression formats, is based on Huffman encoding.

File extension	.7z
Category	Archive File
Description	First released in 1999, the .7z file extension was first released alongside the 7Zip open source archiving application. The format allows for any conversion, encryption or compression method to be applied. Because any of these methods can be used, the format is effectively future proofed. The file type also allows for its size to be extremely large and can achieve high rates of compression.
