To create content within a .rar file (specifically, to add files to a new or existing B&GS.rar archive), you need to use a file archiver utility, most commonly or 7-Zip . Here is how to create and add content to a .rar archive: Method 1: Using WinRAR (Recommended)

If you do not have WinRAR, 7-Zip can create .7z files, or use the "Add to archive" function to create .rar files if the RAR plugin is enabled.

If the files are too large, you can select a "Split to volumes, size" option (e.g., 1GB) to create a multi-part archive ( B&GS.part1.rar , B&GS.part2.rar ).
