Compressed file formats are essential for managing large amounts of data, particularly when transferring files over the internet. The (Roshal Archive) format, developed by Eugene Roshal, is a popular proprietary archive file format that supports data compression, error recovery, and file spanning.

Right-click the of2.rar file and select "Extract Here" or "Extract to [Folder Name]" using WinRAR or 7-Zip.
