WinRARHere is a great file archiver, which will work fine on both 32 and 64 bit Windows operating systems, on the official website you will find versions for other systems. A plus of development can be called a high level of data compression, if you look at the overall rating, this archiver is the leader in terms of speed and compression respectively. I can only recommend everybody to download WinRAR from our project, I use it in conjunction with 7ZIP, everything is quite okay.Naturally with this program you can create archives of formats RAR and ZIP accordingly, and here to unpack files you can absolutely different formats (the full list see on an official site), at creation of archive WinRAR will allow you to cipher it different methods, for example on algorithm AES where length of a key makes 128 bits. If you believe the authors of the program, you will be able to work with archives whose weight exceeds 1000 gigabytes, of course, to create self-extracting, multi-volume and continuous archives, you can also.If you wish, WinRAR will allow you to add additional information to your archives to restore the archive, this can be the case, for example, if it is corrupted, and you can also work with special recovery volumes. You will be able to manage the archiver using the command line, and it works perfectly with the NTFS file system and Unincode file names.Please note that WinRAR since version 4, which you are presented with, has changed the algorithm of archiving RAR, so the developers have significantly accelerated the process of unpacking files. According to them, depending on what files you work with, the speed can be accelerated by thirty percent.
