Opening CNT files
Did your computer fail to open a CNT file? We explain what CNT files are and recommend software that we know can open or convert your CNT files.
What is a CNT file?
Files that contain the .cnt file extension are used by Microsoft Windows to index the help files that are used by the Windows operating system. These files can be created by the Microsoft Help Workshop application, a program that is used to develop help documentation for the Windows OS.
The actual help files that are used by this program are saved with the .hlp file suffix. The table of contents files that organize the HLP files are saved with the .cnt file extension. CNT files are optional files and not all Windows HLP files with have a CNT file associated with it.
Software that will open, convert or fix CNT 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.
