What is an ADT file?
An .ADT file primarily serves as an Advantage Database Table used by the Advantage Database Server. However, the .ADT extension is shared by several other software programs. It can function as an AutoCAD drawing audit report, a map file for World of Warcraft by Blizzard Entertainment, or an ACT! Document Template developed by The Sage Group. Other applications, such as GFI LANguard or Microsoft Word, also create .ADT files for network security logs and document templates.
How to open ADT files?
Because an .ADT file has multiple possible meanings, you should not blindly open it. You must first identify the actual format of your file. An Advantage Database Table requires database management tools like the Advantage Data Architect. An AutoCAD audit log is a plain text file that you can open with Notepad or Vim. Game map files require specialized 3D viewer utilities.
viewer.online/adt analyzes .ADT files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
If you do not know the origin of your .ADT file, do not force it open in a random application. Inspect the file contents safely first. If the file is a document or audio format, you can easily migrate it to a more common standard on convert.guru. For example, you can convert an ACT! Document Template to a .PDF document, or convert an ADTS Audio File to a standard .MP3 file.
Summary
viewer.online/adt directly opens and previews .ADT files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
