Convert RAR Files to BMP in Java

What is RAR file format?

RAR is a file format used for compressing and archiving files. It was developed by Eugene Roshal, a Russian software engineer, and was released in 1993. The RAR format is commonly used for sharing large files due to its high compression efficiency, which can often result in smaller file sizes than other compression methods. This makes it an ideal format for users who need to transfer large files over the internet or other networks.

The main advantage of RAR over other file formats is that it can be used to create multi-volume archives. This means that large files can be split into several smaller files, which can then be combined into a single file when needed. This allows for greater flexibility in storage and transmission, as users can transfer the smaller files more easily and then recombine them later.

RAR files can be password-protected and encrypted for added security. This is especially useful when transferring sensitive data over the internet. When creating a RAR file, users can choose to encrypt it with a password, which will be required to open the file. This makes RAR a popular choice for sharing confidential documents and files.

RAR files are typically identified by the .rar extension, and can be opened using WinRAR, a proprietary file archiving utility. WinRAR is available for Windows, Mac, and Linux operating systems, and supports a variety of compression formats, including RAR, ZIP, and 7Z. It also includes features such as file splitting, password protection, and recovery volumes, which can be used to recover data in case of a file corruption or system crash.

What is BMP file format?

BMP (or Bitmap) is a file format used to store digital images, especially on Microsoft Windows and OS/2 operating systems. It is used to store bitmap digital images, both monochrome (1 bit) and color (4, 8, 16, 24, and 32 bit). The BMP file format is widely used in the Windows world, where it is supported by virtually all the existing graphics applications. The BMP format is a device-independent bitmap graphics format that allows a flexible set of information to accompany the image data. A BMP file includes both encoded image data as well as information about the image, such as its size, resolution and color depth.

The BMP format supports various color depths. The BMP file compression method supports both lossless (uncompressed) and lossy (compressed) formats. Lossless compression saves space without sacrificing quality, while lossy compression sacrifices quality in order to save space.

BMP files are widely used in both professional and consumer applications. Web designers often use them for web page graphics to make their pages look better. They are also used for printing digital photos and for creating computer icons.
