WinRAR is a popular software for creating and extracting compressed files in various formats, such as RAR, ZIP, 7-ZIP, and more. One of the main advantages of WinRAR is that it can reduce the file size of your data by applying different compression methods and settings. In this article, we will explain how WinRAR can reduce file size and how to use it effectively.
Compression is a process of reducing the amount of space required to store data by eliminating redundant or unnecessary information. For example, if you have a text file that contains many repeated words or phrases, you can replace them with shorter symbols or codes that take up less space. This way, you can reduce the file size without losing any information.
WinRAR uses various compression algorithms and techniques to compress files. Some of them are:
Solid compression: This option creates a single compressed stream for all the files in the archive, instead of compressing each file separately. This can improve the compression ratio, especially for similar or related files.
Dictionary size: This option determines the size of the buffer used to store the symbols or codes that replace the original data. A larger dictionary size can result in better compression, but it also requires more memory and processing power.
Compression method: This option determines the algorithm and the level of compression used by WinRAR. There are five levels: Store (no compression), Fastest, Fast, Normal, and Best. The higher the level, the smaller the file size, but the longer the compression time.
Advanced compression: This option allows you to fine-tune the compression settings for specific types of data, such as text, audio, and images. You can enable or disable certain features, such as delta encoding, prediction order, or multimedia compression.
How to Reduce File Size Using WinRAR
To reduce the file size using WinRAR, you need to follow these steps:
Open WinRAR and browse to the folder that contains the files you want to compress.
Select the files and click on Add to create a new archive.
In the Archive name and parameters window, choose RAR as the archive format and select Best as the compression method.
Click on Advanced and then on Compression to access the advanced compression options.
Check Create solid archive and select 1024 KB as the dictionary size.
In the Text compression section, enable Force text compression regardless of extension.
In the Audio compression section, enable Force audio compression regardless of extension.
In the True color compression section, enable Force true color compression regardless of extension.
Click OK twice to confirm your settings and start the compression process.
WinRAR will create a new RAR file with a smaller size than the original files. You can check the compression ratio and the file size difference in WinRAR's status bar.
WinRAR is a powerful tool that can reduce file size by applying different compression methods and settings. By using WinRAR, you can save disk space, bandwidth, and time when storing or sharing your data. However, you should also be aware that some types of files are already compressed or cannot be compressed further, such as JPEG images, MP3 audio files, or PDF documents. In these cases, WinRAR may not be able to reduce file size significantly or at all. 06063cd7f5
