Opening CHM files
Did your computer fail to open a CHM file? We explain what CHM files are and recommend software that we know can open or convert your CHM files.
What is a CHM file?
Files with the .chm extension are most commonly associated with Microsoft help documentation files. The CHM files are compiled to create the help contents of an associated application. These files are normally saved in compressed HTML format and include the images, text and hyperlinks contained in the help files.
The .chm file extension is also used for Chameleon source font files and Chemdraw chemical structure files.
Software that will open, convert or fix CHM files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
