In its common use, the file holds data for Zoo Tycoon 2. It is built with the ZIP container format, meaning its content is compressed.
Some ZTD files are used by racing titles such as MotoGP 20 or Moto Racer 2, where they store game data in a compressed form.

Game Data Archive: It keeps assets like images, sounds, and scripts for in-game functions.

ZIP-based: Its internal structure follows that of a ZIP file, so it can be inspected with a standard archive tool.

Usage: Open it with an archive program (e.g., 7-Zip or WinRAR) or through the game itself if you want to view or modify its content.

FilExt.com tip: Renaming the file extension to .zip often makes it easier to open and explore its structure.

ZTD file format:

The file format determines how the data is stored in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Below you will find our evaluation of the ZTD files:

ZTD is seldom used as a file extension and is mainly used by one program with a specific format. But the following two file formats are common:

• 85% of all ZTD files use the ZIP format, that is, a ZTD file includes multiple compressed files. Such a ZIP file contains 2 to 140 files. Tip: If you rename the file ending to .zip and then double-click it, you see the included files and images. ZTD files are between 1 KB and 41 MB in size. The files contain the following words: animals. Some examples of file names are config.ztd or animals.ztd. Such ZTD files store data about staff, scenario, global, guests and sounds.
• 8% of all ZTD files have the same signature 00 00 00 00 00 00 00 00. These are binary files, so they do not contain words or text. ZTD files can be up to 20 KB in size, but are often around 320 bytes - 15 KB.

The remaining 7% of all ZTD files are files with no common format. If you want to find out which format your ZTD file belongs to, just click on the button "Choose your .ztd file to analyze".
