I'm using an HP Omen 15. Two days ago, I freed up about 112 GB of storage, but today only around 50 GB is available. I've already closed browsers, restarted the laptop, and cleared caches. My previous storage buildup came from editing software autosaves, but I haven't been using that recently. Since freeing the space, I've only played a couple of offline retro games, browsed the web, and downloaded a few files. What could be consuming so much storage, and how can I identify it?

Windows and manufacturer software can create a surprising amount of data through update files, restore points, antivirus logs, crash dumps, temporary files, and backup archives. A visual disk-usage tool should reveal whether one of those folders suddenly grew.
First, check the terminology: this sounds like storage space, not RAM. Use a disk analyzer such as TreeSize, WizTree, or WinDirStat. These tools show which folders and files are taking up the most space, so you can quickly identify whether the problem is downloads, backups, updates, or application data.
If you use classic Outlook, its OST mailbox file can become very large, sometimes approaching 50 GB. The same applies to browser profiles, game launchers, and cached application data, so inspect those folders rather than relying only on Windows’ broad storage categories.
Check whether OneDrive or another sync service is downloading files locally. Also look at your Downloads folder—one or two large videos, disk images, or installers could account for much of the missing space.
