LIT is an ebook format used by Microsoft’s Reader application. It was developed as a proprietary format for electronic books, supporting text, images, and hyperlinks. While it was once popular, the LIT format has been largely replaced by more widely accepted ebook formats like EPUB and MOBI.
RTF is a rich text file format that allows for basic document formatting, including text styles, fonts, and paragraph alignment. It is widely compatible across different platforms and applications. RTF files are ideal for sharing documents that need to maintain formatting but do not require advanced features like those found in DOCX or PDF files.
