Extensions TAR and SIS

The word 'tar' is probably derived as a result of its use in the tapes. The file extension TAR stands for files that came into existence for their usage in backup formats. TAR files were used initially in the devices such as backup tapes and other such back up devices.

However, TAR extension is used differently now. It is used more as a directory extension, to combine files and make them bigger and also perhaps, store them as an archive, or may be as a means to distribute. The extension is more popular with directory and storing dates.

TAR files work differently on different operating systems. If you choose to work with TAR on Windows, you need to take the help of tools to download them. However, it works differently on Linux. Linux features have the compatibility to work with TAR files, and therefore it works best with TAR, without the need of adding additional tools. You should remember that such files have to be unzipped, before you could use them.

Do you know what file extension SIS stands for? 'Sis' stands for 'Software Installation Script'. One of the biggest misunderstandings people have about these files is their assumption of them as application ones. In reality they only work as storage files.

One similarity SIS files have with TAR is the features of archiving, otherwise, SIS files work differently. The format stores Symbian operating system, and the extension files also have been developed by Symbian. One of the significant features of SIS format is its use in mobiles. Mobile phones use this extension to download Symbian operating systems.
