CHM notes

✎ This article/section is a stub — some half-sorted notes, not necessarily checked, not necessarily correct. Feel free to ignore, or tell me about it.

CHM files are single files, compressed and indexed HTML (CHM files can be extracted to a set of HTML and supporting files).

They are often used to store a GUI application's help.

Since a relatively recent windows security update, CHM files cannot be opened across a network (on UNC path or mapped drives. Loading from web servers may also be limited, depending on how the file is actually opened), and the attempt to load their content tends to show "Navigation to the webpage was canceled".

If you trust specific sites, or trust your entire LAN, you can tell each computer to disable the related security measures(verify).
