A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

About .zoo Files

ZOO files are binary files used in two main ways.

Archive Files
Some ZOO files use the MIME type application/x-zoo as archive containers. They bundle one or more files together. This function is similar to other compressed archive formats.


Microsoft Zoo Tycoon Saved Games
Other ZOO files use the MIME type application/octet-stream. They serve as saved game files for Microsoft Zoo Tycoon. This type stores your game progress in a binary format.

Based on information from FilExt.com, the ZOO extension covers these two distinct roles.

Relationship between file extension and MIME type

A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.

File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.

File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs

What are the different types of ZOO files?

There are two distinct formats using the .zoo extension: a legacy compressed archive and a Microsoft Zoo Tycoon saved game. The archive format bundles multiple files together, while the game file stores progress for your virtual zoo.

How do I open a ZOO archive file?

You need a third-party file utility that supports legacy formats, such as ALZip or IZArc. Because the format is older (originating in the 1980s), modern operating systems like Windows 10 or 11 cannot open these archives natively without additional software.

How do I load a Zoo Tycoon save file?

You cannot double-click the file to open it; instead, place the .zoo file into the game's designated save folder (usually within the installation directory or My Documents). Launch Microsoft Zoo Tycoon and select the file from the "Load Game" menu.

Can I convert a ZOO archive to ZIP?

Yes, but you usually must extract the contents first. Open the .zoo file with a compatible tool like IZArc, extract the files to a folder, and then right-click that folder to compress it as a standard .zip file.

What is the MIME type for ZOO files?

The archive format is specifically identified by application/x-zoo. However, game save files are binary and often appear as application/octet-stream. You can look up these identifiers on mime-type.com.

Why can't I open my ZOO file?

You may be trying to open a game save with an archive tool, or vice versa. If your software reports the file is corrupt or invalid, verify the source of the file to determine if it belongs to Zoo Tycoon or if it is an old compressed backup.

Is the ZOO archive format still used today?

No, the ZOO archive format is considered obsolete. It was popular on early DOS systems and Amiga computers but has been replaced by more efficient compression standards like ZIP, RAR, and 7z.

General FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why can one extension have multiple MIME types?

Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
