7-ZIP : HOW TO OPEN RAR FILES
How often we are faced with a file that we downloaded and it to be able to read the files inside. They are the classical files archives. But why do you use compress and decompress them ? Simple, because if, for example, you must send in e-mail or via FTP several files, instead of sending them one by one, we can combine them into one and send only that. Not only, the compression of files, helps, through the use of suitable compression algorithms, to decrease the size of the files themselves.
More files are larger and there is the possibility to reduce its size. Very often we are then faced with the need to pack and unpack archives in RAR and ZIP extensions (most used). We all know WINZIP and WINRAR, free software to open files stored but there are many other freeware and allow you to do the same. Meanwhile, I will list, for those who do not know how many files extensions are around, so that when we find ourselves in front of them, we understand that this is an archive. Here are the types of files more or less common :

Meanwhile, I will list, for those who do not know how many files extensions are around, so that when we find ourselves in front of them, we understand that this is an archive. Here are the types of files more or less common :
CAB, ARJ, LZH, TAR, GZ
TAR.GZ, BZ2, TAR.BZ2, ACE
UUE, JAR, ISO, 7Z, Z, ZIP, RAR
Have you seen those types of files ? Here is a freeware program that serves to open RAR, ZIP, etc... : 7-ZIP. I list its features :
- Small and easy to use.
- Create archives type : 7z, ZIP, GZIP, BZIP2, TAR.
- Allows a file reduction of up to 45% for 7Z archives.
- Files unpack : 7z, ZIP, GZIP, BZIP2, TAR, RAR, CAB, ISO, ARJ, LZH, CHM, Z, CPIO, RPM, DEB, NSIS.
- Protect archives with password.
- Divide a large file into several parts compressible later.
I must say that 7-ZIP is very interesting. It's open source and it's a multilanguage program. In particular, the possibility of creating an archive in its 7-Zip (7z), reducing the files even 45% of their size (on large files), is very useful. But I must say that if it is very high performance has some shortcomings like the encryption and non-existent chance of recovering corrupted files or archives. It's can only create a password to protect archive, however, can be developed in various formats : 7z, ZIP, GZIP, BZIP2, TAR. On the 7-ZIP official site you will find various download versions for WINDOWS, LINUX, MAC.
Anyone interested in other freeware programs to open and create files and archives RAR, ZIP, TAR, etc ..., can read my previous review :
