How to open DLU file?

Step 1. Install 3ds Max

Programs to open DLU file

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

Step 2. Create association of 3ds Max with DLU files

If, despite the installed application, the DLU file does not start in the 3ds Max 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. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the 3ds Max application as the default for handling the DLU file.

Step 3. Update 3ds Max to the latest version

If, however, after binding 3ds Max with 3ds Max Utility Plug-in Format there were still problems, you should update the program to the latest version.

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

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. Usually this applies to DLU 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. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the DLU file that we want to open. As a result of the scan, sometimes it is not possible to recover DLU files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of DLU file may not always be supported by the latest software version. 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. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular DLU file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted file DLU 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. If possible, you can try to move the DLU file to another location.
This problem usually affects more complex files. In this case, the DLU file is blocked by the first application to open it. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the DLU file for a certain period of time. If nothing helps, please reset the device.
