What is a .ibooks file?
A .ibooks file is an Apple iBook format. This is a document format, so it holds text and layout meant to be read.
How to open a .ibooks file
- Try LibreOffice (free, Windows/Mac/Linux) — it opens an enormous range of current and historic document formats.
- Microsoft Word and Google Docs handle most mainstream document types.
- If nothing opens it, open it in a text editor: many older document formats have readable text inside.
The registry records this extension against Apple iBook format, so software from that family is the most likely match.
How to convert a .ibooks file
- Once it opens in LibreOffice or Word, Save As .docx or .pdf to get it into a format you can use anywhere.
