What is a IES file?
Files with the .IES extension contain data on light measurements and its quantity stored in a standardized photometric form devised by IES - the Illuminating Engineering Society.
IES files are used to simulate lighting systems in buildings before their implementation, as well as to study the lighting of roads and outdoor areas. IES files are often published by lighting system manufacturers.

How to open IES files
If you cannot open the IES file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports IES among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the IES file can be found in the table. Now just download and install the appropriate application.
Possible problems with the IES format files
The inability to open and operate the IES file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the IESNA Photometric Data Format file. Below is a list of possible problems.
- Corruption of a IES file which is being opened
- Incorrect links to the IES file in registry entries.
- Accidental deletion of the description of the IES from the Windows registry
- Incomplete installation of an application that supports the IES format
- The IES file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the IES file.
- Drivers of equipment used by the computer to open a IES file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the IES file should operate with your programs without any problem. If the problem with the IES file has not been solved, it may be due to the fact that in this case there is also another rare problem with the IES file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.IES) you have two ways to do it. The first and the easiest one is to right-click on the selected IES file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the IES file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. IES) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
