Portable yBook

Portable yBook is an easy to use text reader that comprises plenty of customization options and support for common formats.

The application has a rather intuitive GUI, with a dedicated settings screen that lets you change paper, ink, highlight and page number colors, borders, line spacing, textures and page turn speed.

It can display a book on a single page or on a side-by-side layout, while pages can be quickly changed with a single mouse click. The app supports text documents, HTML and RTF files, but it's also capable of loading compressed PDB or PRC text files.

A handy search feature is also available to quickly look for a given term, and so is a bookmark manager to save your favorite pages.

As you can see, Portable yBook is a handy piece of software that requires only basic computer knowledge, so many users shouldn't even think about the built-in help section.

Another good thing about this piece of software is that it's completely portable, which means that you can quickly copy all its files on a removable drive and use it on the go without prior installation.

To sum up, Portable yBook is one of the portable apps that are aimed at both beginners and professional users, offering them a very straightforward GUI and lots of customization options. Of course, it doesn't really matter which version of Windows you're running, Portable yBook works smoothly on all of them.
