First thing is to check what's taking up space - usually it's old videos, downloads, or duplicate files you didn't even remember having 😅. You can move stuff to the cloud (Google Drive, OneDrive, whatever you use), delete what you don't need, or if you really need more space, getting an external hard drive is the cheapest and easiest option. You can also clean out your Downloads folder and Recycle Bin, which sometimes pile up a ton without you noticing.
Before moving anything to the cloud, it'd be good to do a local cleanup first because you often have entire folders full of junk - it happened to me that I discovered almost 200 GB of duplicate dashcam videos I didn't even know were there. Once you free up space that way, then you can start thinking about which files to move to the cloud so you have more room on your computer.
