I am approaching a dangerous situation in that my OS (C:) drive is getting more and more full as time goes on. My machine came with a 256GB SSD which was partitioned into a C and D drive. Knowing this, every time I've chosen to install programs, I generally do it to the D: drive in order to save my C: space since it's the OS install. Even still, with all of the MS Windows Updates and also a few tools which wouldn't let me choose their install path (e.g. I have MS Visual Studio and a couple other large programs like this which forced a C: disk install), I am dangerously close to filling the drive and I won't even be able to update my OS anymore. My question is, what can I do to reduce disk space usage on this drive so I can continue to properly use my machine? I am attaching a screenshot of WinDirStat and basically, you can see that the majority of the space seems to be used by Windows system files and AppData. Obviously, I can figure out the personal files I've installed and remove them as appropriate, but I am mainly asking about the system files which continue to grow and grow. For example, in screenshot #2, you can see this "Installer" folder with a bunch of random MSI files. I would like to remove these if they are not immediately needed.
What I've tried so far:
- Run Disk Cleanup, including removal of "Operating System files" which has alreaedy removed the previous version backup file.
- Used 3rd party disk cleanup tools like CCleaner.
- Used WinDirStat to relocate/remove my personal files as needed
By the way, I am looking at getting a new SSD and installing it in my laptop this next week but I also want to do my best to free up the current one that I have.
Is there any way to tell Windows "I am low on disk space so please do not keep throwing more system files/updates onto the drive and consuming it?" For example, I only have 6GB left now and I don't even think I can do the next Windows Update because it'll try to keep a rollback version but won't be able to.
I have access to 3 large (1TB+) external drives and I have created some symbolic links to those before as well but obviously I have to be careful which files I do this with.
