How to open HTMLZ file?

The most common problem when using Zipped HTML EBook is that a specific HTMLZ is not associated with the program. Thus, when you open HTMLZ, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the HTMLZ file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Calibre

In this case, you should first verify that the Calibre application is installed on the computer. The easiest method is to use the system search engine by entering the program name Calibre in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file HTMLZ.

Programs to open HTMLZ file

Remember to download programs supporting HTMLZ files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Calibre with HTMLZ files

If the application is or has been freshly installed, but the HTMLZ file still does not use the Calibre program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the HTMLZ file with the Calibre application.

Step 3. Update Calibre to the latest version

The fault may also lie with the Calibre program, it is possible that Zipped HTML EBook requires a newer version of the program. This can be done using the application (if it provides such options) or from the Kovid Goyal website and install the latest version.

Step 4. Check for the following problems with the HTMLZ file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to HTMLZ files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the HTMLZ file that we want to open. However, remember that not every infected HTMLZ file can be recovered, so it is important to take care of regular backups.
Older version of HTMLZ file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular HTMLZ file corruption. The easiest way to restore the file is from a backup or by contacting N/A, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted file HTMLZ except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the HTMLZ file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file HTMLZ to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
