Electronic publication, to every bibliophile known as EPUB file, is one of the most popular formats used for storing e-books and other types of content. It’s an open XML-based format that provides a standard digital publication for both publishers and consumers. This type of file format is based on three open standards maintained by the IDPF.

What is a ERF file?

ERF or Epson Raw Format file is usually created with Epson digital camera, and it contains unprocessed or raw data. ERF format doesn't have any compression, which means it takes a lot of storage space. A raw format such as ERF is convenient for manipulation of some elements of the image, for example, color ratio, white balance, etc. However, it is common to convert ERF files to a more compatible image format that can be shared, printed, sent, or transferred on a different device, via the Internet or on social media. Besides Epson proprietary software Epson PhotoRAW, to open, edit or manipulate ERF files, you can use Adobe Photoshop, Corel Draw, Windows Photos, ACD Systems' Canvas, and some other known image and graphics apps.
