It looks like you’ve referenced a multi-part RAR archive file — specifically part 36 of a set, likely part of a large split archive (common for 4K video releases).

That being said, I can try to provide some general information or guidance related to the file extension or the concept of archiving.

A RAR file is a type of compressed archive file that can contain one or more files and folders. RAR files are similar to ZIP files but use a different compression algorithm.

Splitting a massive 4K file into 40 or 50 separate parts serves several functional purposes:

To view the content, you cannot simply open "part36" by itself. You must follow these steps:

The primary informative feature of this specific file (indicated by the part36.rar tags) is its Ultra-High-Definition resolution and segmented compression 4K Native Resolution

part36: Because 4K files are so large, they are often split into smaller "volumes" using compression software. This is part 36 of a larger sequence.
