.SDT 文件扩展名

An SDT file is a sound data file used in older Electronic Arts video games, such as Dungeon Keeper 2, Theme Park World, and the Formula One (F1) series. It contains compressed audio data, including background music and sound effects, which the games reference during gameplay. Despite their historical use in popular games, SDT files have become largely obsolete as newer audiovisual formats have emerged.

Most gamers did not encounter SDT files, since the game automatically loaded them during gameplay. However, game modders used tools, like Dragon UnPACKer and MAStudio 2002, to open SDT files and extract audio content, even converting them to more current formats like .MP3 or .WAV for easier use and broader compatibility.

SDT files are not meant to be opened. Instead, the game they are packaged with loaded the files during gameplay.

However, you can open SDT files with Dragon UnPACKer, which can extract and manage game audio files.

An SDT file is an audio file used by Grand Theft Auto III (GTA3), an open-world, action-adventure game. It may contain game music and sound effects, which the game references while running. The SDT format is specific to GTA3 and is no longer actively developed.

SDT files typically reside in the audio folder within the GTA3 installation directory. Players and game modders commonly encounter these files when modifying game audio. Examples of such files include Misbrief.sdt and sfx.sdt.

注: The format is now considered obsolete, with newer games using more advanced audio formats for better sound quality and flexibility.

SDT files are not meant to be opened. Instead, Grand Theft Auto III loads the audio files during gameplay.

An SDT file is a template used by SmartDraw, a diagramming tool for creating business graphics. It stores a blueprint for generating new diagrams in SmartDraw and includes predefined shapes, styles, and layouts tailored to specific document or presentation types. SDT files are helpful for maintaining consistency across various projects, such as flowcharts, organizational charts, and mind maps in business, education, and technical fields.

SmartDraw users create SDT files when saving a diagram as a template to reuse its design elements for future projects. When a new diagram is generated from an SDT file, it inherits the template's components and design settings, allowing users to ensure uniformity in style and structure across multiple documents or presentations.

注: SDT files are typically found in the Documents folder within the SmartDraw installation folder.

You can open SDT files with SmartDraw in Windows and macOS. To open the file, launch SmartDraw and use the "Open" option typically found under the "File" menu. Alternatively, you can double-click the .SDT file if SmartDraw is set as the default application for opening it.

SmartDraw can convert SDT files to various file types, including the following formats:

• .JPG - JPEG Image
• .PNG - Portable Network Graphic
• .SVG - Tagged Image File Format
• .VSDX - Microsoft Visio Drawing
• .BMP - Bitmap Image
• .SDR - SmartDraw Drawing
