User guide

CHM file

When you choose to open an CHM file, Bookr will try to extract the CHM content to the cache folder (no need to extract later).

The extracting job will be executing in background if the CHM contains valid HHC file (table of content); otherwise Bookr will try to extract all htm files first and open the index.htm file as start page.

In worst case, it will list all the htm files extracted. Then the extracting thread will continue to extract all other files such as images, css...

So you may see pages with all images missing at first; but after the Memory Stick LED light stop blinking (indicate 'extracting complete'), please refresh the page to see the full content page.

Bookr opens a Browser with 2 tabs: TOC and Content; please use Square+L/R to switch between them.


Triangle/Square - Next/Previous page

Cross/Circle - Next/Previous 10 pages

D-Pad - Screen up/down/right/left

R/L - Zoom in/out

Start - Menu

Select - Tools
