• Evgeniy Lazarevich Roshal was born on March 10, 1972 in Chelyabinsk — programmer, author of the FAR Manager file manager, the RAR compression format (Roshal ARchiver, which turned 30 this year! ) and the RAR and WinRAR archivers.
• Evgeniy Roshal made his first attempt to write his own archiver called R oshal AR chiver, or RAR for short, in 1991 , but it was not successful — he did not have enough experience and knowledge. But in his final years at the institute, Evgeniy took up studying existing archiving algorithms more closely; he devoted his thesis to the same topic. And these studies brought practical results: the first version of RAR for MS-DOS appeared in March 1993.
• The main feature of RAR compared to another popular archiver for DOS of that time — ARJ , was a convenient mechanism for creating multi-volume archives, including those of a given size. This made it possible to “push” a large volume of files (for example, a computer game) onto several floppy disks, without fear that some file would not fit on the disk. RAR supported the creation of continuous (solid) multi-volume archives, all volumes of which were perceived as a single data stream and unpacked “chain by chain”. In addition, the technology made it possible to create self-extracting (SFX) archives in the form of executable files, which was very convenient if the target computer did not have an archiver.
• Later, the archiver added the ability to create password-protected archives encrypted using the AES algorithm. The algorithm has built-in mechanisms for storing service information, allowing you to restore damaged archives, which significantly increases their reliability.
• The RAR archiver is distributed under a proprietary license, while the UnRAR unpacker has an open license allowing free distribution and use, provided that the program is not used to create a compatible archiver.
• With the advent of Windows 95, on April 22, 1995, Evgeniy released WinRAR , a 32-bit version of his archiver with a windowed graphical interface. This application quickly gained popularity because it supported all the features of the Windows OS — long paths and file names, multi-threaded work and the simultaneous launch of several instances of the application. Now there are versions of RAR for different system platforms besides Windows: macOS, Android, Linux, FreeBSD and others.
• In 2004, Evgeniy transferred all commercial rights to his developments to his older brother Alexander Roshal, who subsequently began to independently control the distribution of his software products, and he himself left Russia. Evgeniy Lazarevich leads a very secluded life, so practically nothing is known about his current occupation. According to rumors, he settled in Germany and later moved to the United States.
• At the moment, Roshal’s archiver continues to be used by millions of people around the world, and FAR Manager is still installed on many computers running Microsoft Windows — this program is preferred by those who are accustomed to the “dual-panel” interface of the classic Norton Commander.
