WinRAR (Winodws)

WinRAR is a program to open, create and decompress RAR, ZIP and other formats.
Functions
WinRAR is a program for "zip" file. Such as WinZip, WinRAR is also a program to compress files so they take up less space on your hard disk.

WinRAR allows you to insert various files of different formats and sizes within the same archive to be able to share so more quickly and easily, via email or chat, for example. But you can also choose the degree of compression of files and decompress files to 14 different formats, including ISO also. It is compatible with Windows 7 and also has a 64-bit version.


In contrast to free alternatives like ZipGenius or 7-Zip, WinRAR is not free, but provides many additional features, for example, allows you to protect the contents of the file with a password to hide the contents from prying eyes.


You can also create self-extracting files or archives that automatically decompress them with a double click on the file: an effective solution especially if you intend to send compressed archives to less experienced.

WinRAR is a very easy to use when it comes to decompress files that are already compacted, and can become a bit 'more difficult for less experienced users to compress the time because of the many options available.

Usability
To open a compressed file, just click with the right button on the archive WinRAR then click Extract one file, and then select the destination. You can directly run WinRAR and, once inside the program, double click on the file you want to "unpack". The extraction of the file can be further simplified by using the button wizard (wizard).

To create a compressed file, however, you can click with the right mouse button and select New / WinRAR Archive, right-click on the file you want to compress and select Add to archive. To create an archive that decompresses itself simply click on the self-extracting WinRAR interface and click OK.

The option of password protection of files with WinRAR may not be enough to protect your files from prying eyes. Keep in mind that there are unfortunately like RAR Password Cracker software that allow you to discover the password. For this reason, if you wanted to make sure you protect the file, you'll want to integrate the program with a software like AxCrypt.
Quality
The obsolete interface is a defect on which you can fly if you're not a fan of the design, especially considering that none of the competitors offers alternatives worthy of note in this field.
Conclusions
Compared to competitors, WinRAR has the best compression ratio and is also the fastest. Also it is quite simple to use and is compatible with 14 different formats (RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z, 7-Zip). WinRAR is also fully compatible with Windows Vista and 7, is in Italian and is integrated with the antivirus on your computer to ensure a higher level of protection. Among the most interesting point out the possibility to repair the file if it is damaged.

If, for your daily use you settle for compression and decompression in a limited number of formats, you can opt for free programs like 7-Zip and ZipGenius. If you need a high degree of compression and more advanced features WinRAR is a natural decision.

RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z, 7-Zip
