What is a .GMW file?
A .GMW file is a type of file that is made and used by a computer program called Global Mapper. Global Mapper is a special tool that helps people work with maps and geographical information. The .GMW file keeps track of all the different parts of a map that you might be looking at in Global Mapper. It remembers things like which pieces of the map are being shown, how they are arranged, and any special settings or adjustments you've made to look at the map in a certain way.
To open a .GMW file, you need to use the Global Mapper program, which is made by a company called Blue Marble Geographics. This program understands how to read the .GMW file and show you the map with all its layers and settings just like you left it.
Think of a .GMW file as a way to save your place in a book. Just like how a bookmark helps you remember the page you were on, a .GMW file helps Global Mapper remember everything about how you were looking at your map. This is really helpful because it means you can close the program and come back later, opening the .GMW file to start right where you left off without having to set everything up again.
To make a .GMW file in Global Mapper, you just need to go to the menu at the top, click on "File," and then choose "Save Workspace." This saves all your current map work into a .GMW file that you can open again later.
