You're looking to free up space on your SSD by removing these system files. Since both pagefile.sys and hiberfil.sys together use up 14GB, deleting them would free 14GB. With a 250GB drive, that leaves you with 236GB available for other files or partitions.
From what I understand, hiberfil.sys is related to hibernation settings. If you don’t enable hibernation, there’s a risk the file could be removed, though it’s not the same as your pagefile swap. Make sure you have a pagefile available (virtual memory) at all times, unless you have an unusually large amount of RAM that remains unused.
