My Acer Predator 16 has a 1 TB SSD, but Windows is installed on a separate 202 GB C: partition. Only about 12 GB is available, even though I don't have many personal files stored there. I have already checked some temporary files, disabled hibernation, uninstalled Copilot, and confirmed Windows is up to date. Restore points use roughly 5 GB, and the page file is managed automatically. What is using the remaining space, and what is the safest way to clear it?

Start by using a disk-usage analyzer such as TreeSize or WinDirStat, preferably run as administrator. These tools show which folders and files are actually consuming the space. Check large areas such as Windows Update leftovers, user AppData folders, crash dumps, installer caches, and virtual memory. Avoid deleting files manually from Windows or system folders unless you know exactly what they are.
Windows Settings > System > Storage can help clean temporary files and old update files. Also check System Protection to see the restore-point limit, and review the page-file size. If the visual analyzer shows that Windows Update or a component store is unusually large, use Windows' built-in cleanup tools rather than deleting those folders directly. With only 12 GB free, avoid installing large programs until you identify the culprit.
Since the SSD is 1 TB but C: is only a 202 GB partition, the missing capacity is probably assigned to another partition. Windows itself can grow considerably through updates, caches, restore data, and the page file, so a 202 GB system partition can fill quickly. After backing up important files, check Disk Management to see whether there is unallocated space or another partition that could safely be used to expand C:. Do not resize partitions without a backup.
The drive has 1 TB overall, but C: was created as a 202 GB partition. I am trying to find out what is filling that partition before changing anything.
Restore points are using only about 5 GB, hibernation is already disabled, and I have checked the temporary-file section. I will inspect the folders with a disk-usage analyzer next.
