TAR and RAR are archiving formats. Although files with the TAR extension are uncompressed, RAR files are compressed files. WinRAR is the primary program used to open RAR documents. On the other hand, TAR files are mainly used by UNIX.
TAR or Tape Archive files are UNIX archive files consisting of many merged documents. Files containing similar data can be easily stored together using the TAR format, making archives easy to create. It stores similar files under one name without changing the individual settings and preferences. Files are packaged together as one unit and are not really compressed. On the other hand, RAR files are compressed data. They have a high compression ratio. RAR is a common extension and can be read with a number of applications. In addition to the standard RAR extension, RAR extensions from R00 to R99 can be performed. This format is mainly used to compress files that are difficult to compress or are already compressed. It is very useful when creating an archive.
The RAR format is very common which is why a number of programs can open it. Some of these programs are WinRAR, 7 zip, UnRar, Smith Micro Stufflt Deluxe 2010, Zipeg and Corel Winzip 14.5. TAR can be opened in applications such as EST Soft ALZip, WinACE, Zipeg, 7 zip, Corel Win Zip 14.5 and Smith Micro Stufflt Deluxe 2010.
The common feature between both formats is that they are mainly used to make archives. The main difference between the two is that RAR files are compressed while TAR files are not compressed. When compressed, they have the GZ extension. They are compressed in the GNU method while RAR files are compressed in the RAR method.
