What is a TEM file?

TEM files mostly belong to Proprietary tools. TEM files are not a single, standard file type. They are used by various programs to store temporary or domain-specific data.
Some common uses are:

• Temporary Data Storage – Some systems create TEM files to hold data temporarily during processing (for example, Neoptix data files used by certain imaging tools).
• 3D Model Data – In specialized cases, a TEM file may contain a 3D face model or data from electron microscopy, which requires specific 3D software to view.
• Geophysical Records – Certain TEM files store Transient Electromagnetic measurements (like the Maxwell TEM data file) that are used in geophysical surveys.
• Industrial Trend Files – Some TEM files act as a temporary storage file in industrial process control, as seen with files from WinCC flexible.
• Game Terrain Maps – They may also serve as a terrain template in games, for example, for maps in titles such as Star Wars: Empire at War.
• Template Files – In other situations, TEM files are used to store preset layouts or data for presentation purposes (such as a Notezilla template file).

Different applications create and read these files. To open or view a TEM file, you must use the application that generated it or an appropriate viewer.
For more details, you might refer to vendor documentation or visit specific pages like NeoScan or FaceGen.

How to open a TEM file

You need a suitable software like Proprietary tools to open a TEM file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your TEM file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a TEM file directly in the browser:. Just drag the file onto this browser window and drop it.

TEM file format:

If you know the file format, you can also find out how to open or edit the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Knowledge is power - this also applies when dealing with unknown or faulty files. Our evaluation of the TEM files is as follows:

As a file extension, TEM isn't very common and has no uniform or dominant file format. However, the following two file formats are common:

• 5% of all TEM files use the same file format, which have the signature 64 6F 03 04 14 00 02 00 08. These files contain neither text nor words, but only data. The files are often between 11 KB and 310 KB in size. Several words can almost always be found in the files, e.g. sznTemCelky.nx1. These files are attributed to biochemie and cele.
• 4% of all TEM files use the same file format, which have the signature 189 . These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. The average file size is 3 KB with most files being between 3.1 KB and 3.5 KB in size.

All other TEM files (91%) have no uniform format. Often described as temp, ansi or template. Just click the "Choose your .tem file to analyze" button on this page to find out what your TEM file is.
