A "full-featured" RAR often includes more than just compression. You can configure these in the archive window:

: Highlight the files or folders you want to compress in your file explorer.

To create a "full-featured" (Roshal Archive) file, you typically need to use the original software it was designed for, WinRAR, as the RAR format is proprietary. Here is how to create a RAR archive with its core features: 1. Download and Install WinRAR

: Use the "Split to volumes, size" dropdown if you need to break a large file into smaller parts for email or USB transfer.

: Set this to "Best" for the smallest possible file size.

: Check "Create solid archive" to achieve significantly higher compression ratios for multiple similar files.
