Ragnarok Online Map File: This file holds map data for the game Ragnarok Online. It stores level geometry and layout information. Visit the PlayRagnarok website for details.
Configuration File: Some GAT files serve as backups of settings for the Check Point Security Gateway. They are often compressed (using ZIP) and used to restore system configurations. More information is available at the Check Point website.
Gator Password / Genealogy Tree File: Other GAT files store password data for Gator Guard or even hold data for family trees used with Genealogy Tree Maker. Opening these files requires the respective application.

How to open GAT files

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.

Programs that open and convert GAT files:

Ragnarok Online
See the previous paragraphs to learn more about the main application. GAT files are often referred to as Ragnarok Online games because this type of file is primarily created or used by this software.
Gator File
(password manager)
Genetic Algorithm Timetabler (GATTer) (Configuration and Information File) by Chris Skardon
GATTer allows the creation of simple exam timetables based on two key inputs from the user, providing output in a suitable format, as a file on the user’s disk space. The output includes the date, time and location of each course’s exam. This file format is classified as Text.

GAT format details:

If you know the file format, you can also find out how to open or edit the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the GAT files is as follows:

GAT is seldom used as a file extension and is used by a few programs, each with its own file format. The file formats most commonly found in GAT files are:

35% of all GAT files use the same file format, which can be identified by the letters "GRAT" at the beginning. These files are binary files, so they do not contain text, but only cryptic characters. The file size is in the range of 390 KB to 2 MB. This file type is based on cutting-edge technology. The keywords GRAT are typical for these files. Files like these are sometimes connected to fild.
30% of all GAT files use ZIP compression, the GAT file contains a number of compressed files. The average file count is 171 with most GAT files containing between 1 - 230 compressed files. File names inside are always \object\conf\Zebra.conf, \object\conf\arp_spoof_db, \object\conf\auth_ldap.conf, \object\conf\auth_radius.conf, \object\conf\auth_tacacs.conf, \object\conf\chap-secrets, \object\conf\cron.update, \object\conf\dhcpd.conf, \object\conf\firewall_nat.policy, \object\conf\firewall_nat.policy.tmp, \object\conf\firewall_natpt_ipv1.policy and \object\ips.sql. If you want to see the included files and images, simply rename the file extension to .zip and double-click it. The files are often between 9 KB and 91 KB in size. Several words can almost always be found in the files, e.g. object/UT. The file name object.gat is typical for these files. These files are attributed to future.

All the rest of the GAT files (35%) have different formats. Often described as gator. If you want to find out which format your GAT file belongs to, just click on the button "Choose your .gat file to analyze".
