Description
The FBZ file type is associated with FlashBack Screen Recorder, a program developed by Blueberry Software. It is used to store screen recordings captured with the FlashBack application. These recordings can include video of the screen, audio, and even webcam footage, making it a versatile tool for creating tutorials, presentations, or any content that requires capturing on-screen activity. The FBZ file format is specifically designed for use within the FlashBack software, allowing users to edit, save, or export their recordings.
A KEPUB file is an EPUB ebook with extra Kobo markup (koboSpan elements and a kobo.js script) that Kobo e-readers use for their faster renderer, page statistics and highlighting. It is usually saved as .kepub.epub; any EPUB reader can open it.
