How to open CHAP file?
The most common problem when using MP4 Movie Chapter is that a specific CHAP is not associated with the program. This causes the file CHAP to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the CHAP 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 DVBPortal MP4Muxer
In this case, you should first verify that the DVBPortal MP4Muxer application is installed on the computer. This can be achieved by typing DVBPortal MP4Muxer into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open CHAP files.
Programs to open CHAP file
Remember to download programs supporting CHAP files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of DVBPortal MP4Muxer with CHAP files
If the application is or has been freshly installed, but the CHAP file still does not use the DVBPortal MP4Muxer program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. 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 CHAP file with the DVBPortal MP4Muxer application.
Step 3. Update DVBPortal MP4Muxer to the latest version
The fault may also lie with the DVBPortal MP4Muxer program, it is possible that MP4 Movie Chapter requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the DVBPortal page and install.
Step 4. Check for the following problems with the CHAP file
Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:
The CHAP file may be unusually small compared to the original file. This is most often caused by a problem while downloading the CHAP file. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the CHAP file that we want to open. As a result of the scan, sometimes it is not possible to recover CHAP files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the CHAP files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
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 CHAP file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
The program indicates that the file is encrypted or corrupted. The encrypted CHAP files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. Copying the CHAP file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the CHAP file is blocked by the first application to open it. Just close unnecessary programs. Sometimes you have to wait for the session to the file CHAP 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.
