How to Load PRC Files on an iPhone
- 1). Determine whether your file is an ebook. If it is, your file does not require any conversion before the transfer, though you will still need appropriate ebook software, such as Bookshelf or Files, to read it.
- 2). Convert your database file if it is not an ebook. The tools you will use depend on how the original file was demarcated. Find a conversion utility that suits your needs, such as Ecamm's PalmFileEdit or the Amber Palm File Converter (see Resources).
- 3). Import your PRC file and set the output format.
- 4). Output your iPhone-readable file using your chosen utility.
