On Windows 10/11, Xbox game captures that are recorded on the PC with Xbox Game Bar are saved locally under:
Videos → Captures
Each recording is an MP4 file; screenshots are PNG files. The file name includes the game/app name and the date and time of the recording.
To open them quickly on Windows:
- Open File Explorer.
- Go to Videos.
- Open the Captures folder.
If the captures were created directly on an Xbox console (not the PC), they are stored on the console and/or Xbox network, and the steps to download them from the console or Xbox apps are not covered in the provided material.
