Opening W3G files
Did your computer fail to open a W3G file? We explain what W3G files are and recommend software that we know can open or convert your W3G files.
What is a W3G file?
Files that contain the .w3g file extension are normally associated with the Warcraft III gaming application. The Warcraft III computer game, distributed by Blizzard, is a real-time strategy game that allows users to play one of four different races (orcs, humans, undead and night elves) in an effort to thwart the Burning Legion.
The W3G files that are used by this gaming software are used to store game replay files. These files contain the activity of a game play scenario and are saved automatically to the program's installation folder.
Each time the game is played, the W3G file is automatically updated.

Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
