How to open HDRU file?
An often recurring problem with Apollo HRDU Image Format is that HDRU is not associated with the correct program file. This causes the file HDRU 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 HDRU 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 XnView
In this case, you should first verify that the XnView application is installed on the computer. The easiest method is to use the system search engine by entering the program name XnView in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file HDRU with XnView. Below is a list of programs that support the file HDRU.
Programs to open HDRU file
Remember to download programs supporting HDRU files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of XnView with HDRU files
However, it may happen that the application itself does not cause the HDRU file to open in the XnView application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. 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 HDRU file with the XnView application.
Step 3. Update XnView to the latest version
If, despite the association of the XnView program with the Apollo HRDU Image Format file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Pierre-Emmanuel Gougelet page and install.
Step 4. Check for the following problems with the HDRU file
Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:
The affected file may be 0 KB or smaller than expected. This suggests truncating the HDRU 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 virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file HDRU or the program directory. However, remember that not every infected HDRU file can be recovered, so it is important to take care of regular backups.
Older version of HDRU 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. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged HDRU files. The easiest way is to restore the file from a backup, if there is one, or contact N/A
When reading, a message appears that the file was encrypted or corrupted. The encrypted HDRU 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. 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 HDRU file to another location.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the HDRU file again. However, some background programs may block the HDRU file while scanning. If nothing helps, please reset the device.
