If your physical RAM starts to fill up, Windows uses what's called a page file or swap file. Not every installed program keeps its information here, but many do. Thus, if you head into the Program Files folder, you'll find folders for most programs you have installed. During this time, the app creates an entry for itself in the Program Files folder, adds Registry values, and performs other tasks that it needs to work properly on your system. Whenever you install software, you usually open up an EXE file and run through an installation process (if not, you're using a portable app). Located at C:\Program Files and C:\Program Files (x86) Let's discuss some places that most users shouldn't mess with when they're looking through the Windows file system. Messing with these could result in an unstable system, loss of data, or other negative consequences. However, there are several other Windows default files and folders that you should leave alone. With a bit of searching, you can find hidden Windows caches that are safe to clear if you need to reclaim space. In addition to your personal files and folders, the Windows OS itself takes up a lot of space on your computer.
