Although the format was designed by Microsoft, it has been successfully reverse-engineered and is now supported in many document viewer applications. Within the Windows NT family, the CHM file support is introduced in Windows NT 4.0 and is still supported in Windows 11. It was introduced as the successor to Microsoft WinHelp with the release of Windows 95 OSR 2.5 and consequently, Windows 98. The format is often used for software documentation. The files are compressed and deployed in a binary format with the extension.

Microsoft Compiled HTML Help is a Microsoft proprietary online help format, consisting of a collection of HTML pages, an index and other navigation tools. why it did not show up as a problem even with massive chm files except freecommander.chm is beyond me but at least it now works as it is supposed to.Microsoft Compiled HTML Help Developer(s) This real wacky but it resolved the problem. Then the help file opens with images showing. Set a cache location and then I could adjust the size. Then noticed there was no cache loaction. In IE 11 i tried to adjust the cache and kept getting this message must be between 8 and 8 meg. However when opening the file in freecommander with F1 is still opens with no images showing just placeholders until the menu 'options, refresh' is applied to each page. If i use my file search utility 'everything.exe' to display a list of chm files they all open showing images including Freecommander.chm. Also tried to open up the internet explorer security zones which I believe loads the chm files. The refresh from within the page right click does not resolve only the menu refresh does it. I have made sure chm file exits in the install as well as the app/user/local directory as well. I have used hhreg.exe to register the files and again in different locations still do the same thing. I have 'unblocked' the file, and problems also occurs in any other directory too. However any page with images just need to top menu 'option refresh' the page and up it comes with images. As images appear on most pages its a problem. However the F1 help file opens the file and displays it with out any image. Windows 10 64 bit desktop with Freecommander XE donor 700 (and all previous versions too)Ĭhm help file is installed along with the program that works fine. Strange problem here and seeking any suggestions please.
