Acer Predator Helios Neo 16 storage is full or nearly full

The checks in more detail

but check the model's specification and the slot's speed in Acer's documentation before buying, and note that opening the base may have warranty implications. PredatorSense and the NVIDIA app keep caches and recordings: the NVIDIA overlay's replay clips can take many gigabytes, so check their folder. Windows keeps hibernation and update files, which the Disk Cleanup tool removes. Move videos and downloads to an external drive. Keep ten percent free so Windows and games run well.

Steam, Epic and other launchers each keep a download cache and shader cache that grow over time, and clearing them in each launcher's settings frees gigabytes. Shader caches in the NVIDIA control panel can be reduced too, though games rebuild them and may stutter at first. It also helps to check where game saves and mods go, since mod folders for large games can reach tens of gigabytes, and to look at the Windows.old folder after a major update, which Disk Cleanup removes once you are sure the update is stable.

Sort folders by size with a disk analyser to find what is large before deleting anything. If a game needs a fast drive, keep it on the SSD and move older games to an external SSD or a second internal drive, and use the launcher's move-install feature rather than copying folders by hand. Run a trim in Windows (Optimize Drives) after large deletions so that the SSD recovers its speed.
