Frequently asked questions
What is a .fb2 file?
An XML-based ebook format popular in Russia and Eastern Europe, storing text and metadata separately from formatting.
Can I edit a .fb2 file?
Partially. .fb2 files can be edited with the right tool (such as Calibre), but not with just any text editor.
Does having a .fb2 extension mean the file is safe?
No single extension can guarantee that. Plain documents are generally low-risk to view. If the format supports macros or embedded scripts, keep them disabled unless you specifically expect and trust them. Always consider where the file came from, not just its name.
