What are the unmovable files?
Unmovable files refer to the data generated by Windows that cannot be automatically moved by Windows built-in tool Disk Management, such as Hibernation, Page file and System protection. You cannot see these files in File Explorer, because they are hidden by default. Therefore, when you try to shrink a volume with unmovable files, Disk Management in Windows 10 gives you a really small space to shrink or even none. To shrink volume with unmovable files, you can manually disable Hibernation, Page file and System protection files, or use third-party partition software that can automatically move the unmovable files.
Manually disable the unmovable files
As the tip given that you cannot shrink a volume beyond the point where an unmovable files are located, you need to manually remove the unmovable files. First of all, you need to show hidden files, so you can view these unmovable files. The easy and universal way for Windows 7/8/10/11 is via Windows’ search. Search “show hidden files and folders” and open it to uncheck Hide protected operating system files (Recommended) and check Show hidden files, folders, and drives.
To work this around, you need to disable the system files as many as you can at this very moment.
Second, disable System Protection and run Disk Cleanup and Disk Defragment. You can easily find them from the Windows search box.
Third, run the command “powercfg /hibernate off “from a command prompt to disable hibernation.
Fourth, disable the kernel memory dump. Go to Advanced Settings/ Startup and Recovery /Settings, and then change the drop-down menu under Write debugging information to “None”.
Fifth, disable page files in Control Panel\System and Security\System\Advanced system settings\Settings under Performance\Advanced\Change, and delete c:\pagefile.sys files in File Explorer.
After that, you should be able to shrink your partition with a larger amount of space.
