By treating files as a single block, WinRAR can find patterns across multiple files, significantly reducing the total size. This is common for game repackages (like Icarus ) that contain many similar small files.
In the context of WinRAR and multi-part archives like your file, a solid feature (Solid Archive) is a special compression method where all files in the archive are treated as one continuous data stream. What it means for your file
Are you seeing an during extraction, or were you just checking if the file is safe to open?
In a multi-part set (like .part03.rar ), if one part is corrupted, it is much harder to recover data from the subsequent parts compared to a non-solid archive. How to handle it
Updating or modifying a solid archive is slower because the software has to re-analyze the entire data block.
Because the data is linked, you cannot easily extract a single file from the middle of the archive without WinRAR processing everything before it.
