Yesterday my 1TB SSD had roughly 400GB of free space, and I had even removed a few games to clear up storage. Today Windows reports that only about 1GB is available, even though I haven't knowingly downloaded or installed anything since then. I also have a separate 1TB hard drive. What could be using hundreds of gigabytes, and how can I find and safely remove it?

Check Installed Apps or Add/Remove Programs and compare the listed application sizes with what the drive is reporting. Large games and launcher libraries can sometimes be stored in a different folder than expected. If the storage-usage tools show far less data than Windows claims, inspect hidden and protected system files and then run a drive-health check, since a reporting or hardware problem is possible.
Windows can use a surprising amount of space for updates, logs, system restore data, crash dumps, and temporary files. Also check the Recycle Bin and the storage breakdown in Settings, because some deleted files may still be retained there. The storage category should help confirm whether this is applications, system files, temporary data, or something else.
Start by using a disk-usage tool such as WizTree, WinDirStat, or TreeSize Free. Run it as administrator and check which folders are actually consuming the space. Pay particular attention to game libraries, downloads, temporary files, system restore points, update files, and the Recycle Bin. Since the drive is 1TB, losing nearly 400GB is unusual, so identifying the largest folder is the first step. If the tools cannot account for the missing space, then check the SSD's health and whether Windows is reporting its capacity correctly.
Either can work, but WizTree or TreeSize Free is usually faster. The important part is to scan the correct SSD and run the program with administrator privileges.
Would WinDirStat or WizTree be better for checking this?
