How to open ULD file?
The main problem with Unified Luminaire Datafile is that the ULD file is incorrectly associated with programs. This is manifested by the fact that ULD files open in unusual applications or do not have an assigned program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the ULD 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 DIALux
An often overlooked issue is to make sure that DIALux is installed on the computer. The easiest method is to use the system search engine by entering the program name DIALux in it. 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 ULD files.
Programs to open ULD file
Remember to download programs supporting ULD files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of DIALux with ULD files
If, despite the installed application, the ULD file does not start in the DIALux application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. 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. Checking the "Always use the selected program ..." box will permanently associate the ULD file with the DIALux program.
Step 3. Update DIALux to the latest version
If, despite the association of the DIALux program with the Unified Luminaire Datafile 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 DIAL GMBH page and install.
Step 4. Check for the following problems with the ULD file
The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:
The ULD file may be unusually small compared to the original file. This suggests truncating the ULD file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the ULD file that we want to open. Sometimes virus-infected ULD files cannot be recovered, so make a backup in advance.
Older version of ULD file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair ULD file corruption. The easiest way is to restore the file from a backup, if there is one, or contact DIAL GMBH
When reading, a message appears that the file was encrypted or corrupted. The encrypted ULD 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 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. Copying the ULD file to another location will fix the problem.
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. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file ULD to close. Some anti-virus or backup software may occupy the ULD file for a certain period of time. If the problem persists, restart the machine.
