XFr

Could you clarify what XFr refers to? The term could describe different things (a company, a technology standard, a fictional concept, a product name, etc.), and there is no single universally recognized article. If you specify the domain or provide a brief description, I can write a concise, neutral wiki-style entry under 300 words.

If you’d like, I can also provide one of the following:

- A disambiguation-style note outlining possible meanings and directing readers to domain-specific articles.

- A neutral, hypothetical article for XFr as a fictional technology, clearly labeled as fictional.

- A concise, real-world entry if you provide a verified context or source.
