Compiled HTML is an ancient electronic book format with a .chm file extension. We are all familiar and used to popular alternatives like Portable Document Format (.pdf), EPUB, and Mobipocket (.mobi).
Few days back, I downloaded a chm eBook, when I opened it for reading on my Windows 7 PC (you don’t need any reader to view a chm book as it is supported internally by Microsoft Windows), the content wasn’t visible or rather it was hidden.
If you ever encounter this problem, it just a matter of seconds to get it fixed as outlined below;
- Right-click the CHM file and click Properties
- Click the
unlockbutton, Apply and then OK.
- Open the chm file and the content should now be visible for reading.
