What is a THU file?

THU files mostly belong to Image Viewer. THU files are used in two main ways.
One use is to store image thumbnails. These files contain preview images in either JPEG or PNG format. Software from LEAD Technologies Inc. V1.01 and Adobe ImageReady creates these files to show a smaller version of a larger image quickly.
Another use is in gaming. In titles like Command & Conquer: Generals, THU files act as texture archives that store game images for rendering. They are associated with systems such as THUG Pro. More information can be found on the official game page.
Key details as outlined by FilExt.com:

Formats: They use common image standards (JPG and PNG).

Thumbnail Role: Provide quick previews in applications.

Game Texture: Serve as archives for texture data in games.

Viewing: Standard image viewers or the game's engine can display them.

Conversion: Renaming the extension to .jpg or .png may allow you to open them with basic image software.

How to open a THU file

You need a suitable software like Image Viewer to open a THU 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 THU file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a THU file directly in the browser:. Just drag the file onto this browser window and drop it.

THU file format details:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be deduced from the file extension and the signature. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Exact knowledge of the format is therefore important in order to solve problems occurring in files. In the following you will find our evaluation of the THU files:

The THU file extension is not found very often and includes different formats for different programs. The two most popular formats are as follows:

• 60% of all THU files internally utilize the JPG file format. JPEG is the standard image format for lossy and compressed image data. These files contain neither text nor words, but only data. The files are often between 3 KB and 41 KB in size. The file type is very old but is also used today. The files contain the following words: JFIF, LEAD Technologies Inc. V1.01, '''''''''''', + "&'))), -0,(0$()' and Exif. The following filename is common: DSC00000.thu or EDCM0000.thu. These files are often associated with murrell, and have often person-related content.
• 8% of all THU files start with the magic bytes TH, which are always the first bytes of this file format. The contents of these files cannot be read by a human; only a computer program can interpret the data. THU files are between 4 KB and 180 KB in size. The file name always.thu or M01.thu is typical for these files.

All other THU files (32%) have no consistent format, such as PNG. If you want to find out what your THU file contains, drag and drop it onto this page.
