Quick answer: Old NVIDIA installer folders may be removable, but driver components and active shader cache should be handled carefully.
Why this uses C drive space
GPU drivers and game shader caches can use disk space after repeated driver updates. Some files are installers, while others are active caches.
Safe cleanup steps
- Check installed NVIDIA driver version first.
- Remove old downloaded driver installers from Downloads.
- Use GeForce Experience or NVIDIA installer options for clean installs when needed.
- Let games rebuild shader cache if you clear it.
- Restart after driver cleanup.
What to avoid
Do not delete active driver folders from System32, DriverStore, or Program Files manually.
