What is a GUIDS file

GUIDS files mostly belong to Euro Truck Simulator 2. GUIDS files are specialized internal files used in games like Euro Truck Simulator 2. They are designed to serve as an asset index and mod file container.
These files hold detailed metadata and are used to connect unique game asset identifiers with their corresponding data. This function is essential for linking in‐game assets to audio data, such as sound bank information that FMOD Studio manages.
Key points compiled by FilExt.com include:

Game Asset Index: They map unique identifiers to various in‐game items and assets.

Audio Metadata Container: They store information for audio sound banks, which is critical for efficient sound management.

Mod File Use: They are used in mod files to enable modifications and customizations in Euro Truck Simulator 2.

FilExt.com tip: For further details, visit the Euro Truck Simulator 2 official site or ETS2 mods page.

How to open a GUIDS file

You need a suitable software like Euro Truck Simulator 2 to open a GUIDS file.

Programs that open and convert GUIDS files:

Euro Truck Simulator 2
See the previous paragraphs to learn more about the main application. GUIDS files are often referred to as Euro Truck Simulator 2 games because this type of file is primarily created or used by this software.
FMOD Studio
The .GUIDS file extension is primarily associated with game asset indices, specifically within the context of audio metadata. These files often contain structured data that maps globally unique identifiers (GUIDs) to corresponding game assets, commonly audio files. .GUIDS files are frequently employed to manage and organize sound effects and music within game development. While they can be found in various game engines, they are notably prevalent in projects utilizing the FMOD Studio audio middleware. Within FMOD Studio, .GUIDS files play a crucial role in linking audio events and banks to their respective assets, enabling efficient sound management and playback within the game. This file format is classified as Game Development.

GUIDS file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Knowledge is power - this also applies when dealing with unknown or faulty files. Our examination of the GUIDS files comes to the following conclusion:

The GUIDS file type is used by a few programs, each with its own file format. The two most common formats are as follows:

45% of all GUIDS files start with the bytes 7B 31 crucial for this file format. The contents of these files can even be read by a human. Most of these files are 2 KB to 4 KB in size. This file type is based on cutting-edge technology. The files contain the following words: {1315eda7-1829-4dd8-9d1a-176f65637ab2} bank:/master and {8b08cd73-6952-019a-1b53-9d9194907c2a} bank:/master.strings. An example of a file name is scania_2016_v8.bank.guids. These files are often associated with bank, scania, zeemod, mercedes, russian, volvo, yandex and skoda.
8% of all GUIDS files start with the bytes 7B 65, which are crucial for this file format. These files contain text and words, not binary data. The average file size is 5 KB with most files being between 2 KB and 8 KB in size. Several words can almost always be found in the files, e.g. {07a9d24f-154b-4089-9231-187ff9d2f849} bank:/air_horn_03, {0b97ac33-a98b-414c-b995-f and {ed82347d-ab57-4769-9a68-11b60b02427c} bank:/air_horn_01. Examples of file names are air_horn_01.bank.guids.

All the rest of the GUIDS files (47%) have different formats. They are often associated with kriechbaum, interior, effects, english, actros, original or cummins. Drag & drop your file here to see the file format and a preview of your GUIDS file!

How to solve problems with GUIDS files

Associate the GUIDS file extension with the correct application.
Update your software that should actually open metadata containers. Because only the current version supports the latest GUIDS file format. Search, therefore, e.g. on the manufacturer website after an available Euro Truck Simulator 2 update.
To make sure that your GUIDS file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
