Archivers installed on machines with a processor over 2 GHz compress one megabyte of information in one second, and unpack up to twenty megabytes in one second.

Archiving a file is quite simple - follow your intuition and common sense. It should be noted that the maximum compression file will, if you specify the method of archiving LZMA. If you wish, you can put a password on the archive or make a self-extracting exe-shnik.

A very useful feature of the program is the ability to split the file into several parts. This helps when processing large videos. For example, if you downloaded a movie in widescreen quality, then, most likely, the size of the movie will not allow you to burn it to DVD as a whole. To do this, split the film into several parts using our archiver and burn it to disk separately. It is important to specify the degree of compression "ultra" and choose the size of the parts into which the film is divided, as "DVD".

To ensure that the files are compressed or broken down correctly, you can use the integrity check function. To do this, select the file that requires verification, find the item “Test” in the menu and click. The result of the check will be a window with errors found or missing.

For experienced users, of particular interest is the function that allows you to determine the checksum (CRC and SHA-256) - this is another way to check the correctness of the data obtained using the archiver.

Having bought a licensed disc with the operating system or software, you can notice the prescribed code consisting of Arabic numerals and Latin letters - this is the checksum that confirms the authenticity of the source.

Simply put, the checksum is a guarantee of product quality. The code found will tell you that the file has not been subjected to hacker attacks and does not contain malicious viruses. You can register such code for your own file if you right-click on it and select “Checksum”. The code for your source code will appear in the pop-up window.
