yBook is an ebook reader developed by Spacejock Software for Microsoft Windows. The program uses YBTXT as one of its ebook formats.
A YBTXT file stores ebook content in a format intended for use within yBook. It is a software-specific ebook file rather than a general-purpose ebook format, so support outside yBook may be limited.
Install yBook on Microsoft Windows, then open the YBTXT file from the program's Open command. If yBook is installed and associated with the YBTXT file extension, double-clicking the file may open it automatically.
Open the file in yBook to read its contents. If the original source document is available, convert that source to the required ebook format instead.
