What is IES file?

The file in the IES format belongs to the Data Files category. The creator of this file is Illuminating Engineering Society. Additionally, the Data Files category contains 1326 of other files. IES Photometric Data Format appears on 1 operating systems as a functional file. The file will work on Windows systems, unfortunately not on others. The Revit Architecture application is recommended to open the file. It was released by Autodesk, Inc.. This file type can also be opened by 4 other programs. 3ds Max, RenderZone, ZEMAX, EulumdatTools will apply when it is not possible to use Revit Architecture.

How to open IES file?

The most common problem when using IES Photometric Data Format is that a specific IES is not associated with the program. This causes the file IES to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the IES 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 Revit Architecture

The first step is to check if the computer has the Revit Architecture program installed. This can be achieved by typing Revit Architecture into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file IES with Revit Architecture. Below you will find a list of applications that support IES files.

Step 2. Create association of Revit Architecture with IES files

However, it may happen that the application itself does not cause the IES file to open in the Revit Architecture application, but you can set it manually. 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. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the IES file with the Revit Architecture application.

Step 3. Update Revit Architecture to the latest version

If, however, after binding Revit Architecture with IES Photometric Data Format there were still problems, you should update the program to the latest version. In this case, use the Autodesk, Inc. website or update the program from the application.

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

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the IES file. 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. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file IES or the program directory. As a result of the scan, sometimes it is not possible to recover IES files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the IES file. 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. Some programs offer the option of recovering data from damaged IES files. The easiest way is to restore the file from a backup, if there is one, or contact Illuminating Engineering Society
The program indicates that the file is encrypted or corrupted. The encrypted file IES 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. The problem is only writing to the file, not reading it. Copying the IES file to another location will fix the problem.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file IES to close. However, some background programs may block the IES file while scanning. If the problem persists, restart the machine.
