Last week, I noticed that my C: drive was running low on storage, with a little over 25GB of space left. First, I deleted a couple of large files from the Downloads folder, and it helped me reclaim 11GB. Even then, I barely had 36.5GB free on a 306GB volume. That got me wondering, what’s taking up all that space? I don’t install a lot of programs. It’s usually a few that I regularly need. And even with Windows taking up close to 40GB, there should be more free storage. Additionally, I have an external SSD that I can transfer files to. But even for that, I have to figure out which files can be moved without affecting the system’s stability. So, I spent the next few hours exploring built-in and third-party utilities, and by the end, I had over 120GB of free space on the system partition.
