What is a DLG file?

DLG files mostly belong to Game engine. A DLG file is used to store dialog or log data. In many cases, it holds conversation scripts for video games. For instance, games like The Talos Principle, Dragon Age: Origins, Vampire: The Masquerade and Deus Ex: Human Revolution use these files to manage in‐game dialog.
Other programs use the DLG format to record system or call logs. Examples include docking logs from simulation tools such as AutoDock and log files from dive computers or data logger systems.
The internal structure can vary. Some files are written in plain text (using encodings like UTF-8) while others are stored in compound or compressed formats (e.g., using zlib or even as SQLite databases).
If you have a DLG file, you should first check which application created it. For game-related files, the game engine loads them automatically. For logging files, a simple text editor might be enough.
  • Back up the original file before making any changes.
  • Verify the file encoding if unexpected symbols appear.
  • Use the specific software or game engine to open and view the file.
  • How to open a DLG file

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

    Programs that open and convert DLG files:

    1. Game engine
      See the previous paragraphs to learn more about the main application. DLG files are often referred to as Game engine games because this type of file is primarily created or used by this software.

    3. BioWare Aurora Engine (Conversation) by BioWare Corp.
      A Conversation is a branching set of predefined text strings ("lines") that a player and one or more NPCs can say to each other, along with the conditions that govern which lines are said and which are not, which are available to say and which are not, and the actions that accompany each line as it is said. Conversations are stored as .dlg files, and may be present in global game resources in BIF files, in the override directory, in a module, or in a savegame. Conversation files use BioWare's Generic File Format (GFF).

    DLG file format:

    If you can determine the file format, the associated program can also be determined. The file format can be deduced from the file extension and the signature. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the DLG files is as follows:

    You will often come across the DLG file type. This is used by different programs with different formats. However, the following two file formats are common:

    The remaining 65% of all DLG files are different files with different signatures, such as UTF-8, XML, DOC, CAP, zlib, GFF and dlg. These files are often connected to screen, overlay, auto, data, tutorial, message, tower, game, male or text. If you want to find out which format your DLG file belongs to, just click on the button "Choose your .dlg file to analyze".

    How to solve problems with DLG files

    • Associate the DLG file extension with the correct application.
    • Update your software that should actually open data files. Because only the current version supports the latest DLG file format. Search, therefore, e.g. on the manufacturer website after an available Game engine update.
    • To make sure that your DLG file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
    • Click here to open your .DLG file online - secure, fast, and no downloads needed.
