We’ve previously covered the standard ways to free up space on Windows. But if you have a small solid-state drive and really want more hard space, there are geekier ways to reclaim hard drive space.
Reducing the Page file is actually not a good way to free up space. Simply put, your Pagefile should never be less than a gigabyte. It should never be more either,
You know, when you're like me and you have a 500 GB drive with 80 GB used, you actually feel nice when you see such articles.
Nice one, but my page file is already 1 GB, hibernation is required, and everything else I have done before.
On the page file I would make 2 suggestions.
First is set the swap file size to constant, rather than let system resize as needed. Before you change the setting, use Task Manager to monitor how much space you use in it over a period of time.
Second, after you set the size to constant, defragment it. The swap file can only be defragemented during boot time, when it is not in use by Windows.
The default setting of letting the system resize it caused the page file to be setup in many fragments. Those page file fragments are not moveable the the regular defrag, so you end up breaking up contiguous free space, causing other files to fragment also.
