Step 2. Create association of Windows Notepad with HTML5 files

If, despite the installed application, the HTML5 file does not start in the Windows Notepad application, you must create a file association.

Step 4. Check for the following problems with the HTML5 file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This suggests truncating the HTML5 file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file HTML5 or the program directory. However, remember that not every infected HTML5 file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the HTML5 file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair HTML5 file corruption. You can restore the file from a backup or use N/A help.
The program indicates that the file is encrypted or corrupted. The encrypted file HTML5 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. These directories are write-protected to them and it's very hard to fix this problem. It is best to move HTML5 to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the HTML5 file again. However, some background programs may block the HTML5 file while scanning. If nothing helps, please reset the device.
