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 PPSX file format?

PPSX is a Microsoft PowerPoint Open XML Presentation file type. It is similar to PPTX, but differs in that it contains a single slide that is meant to be viewed as a slideshow. PPSX files are generally used when sharing a presentation with a large group of people, or when creating a presentation that is meant to be played on a projector or TV. The PPSX format is similar to a PPTX file but contains a slightly different format structure than a PPTX file.

The PPSX file format is based on XML, making it a more versatile format than the PPTX format. It is compatible with many versions of Microsoft PowerPoint, as well as Apple’s Keynote software. PPSX files can be opened on any platform that supports the Open XML Presentation format, and can be viewed on computers, TVs, or projectors.

PPSX files are a great option for those who want to share a presentation with a wide audience, such as those attending a webinar or virtual meeting. Since the PPSX format is based on XML, it can also be used for easy editing and versioning of presentations.
