What is the QHCP file format?
A file with the .QHCP extension is a file known as Qt Help Collection Project. This format is associated with Digia Oyj.
The reliable way to open a .QHCP file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .QHCP files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
