A 128 or 256 GB PC works with four decisions made once

On a 128 or 256 GB machine, Windows and a normal set of software take a large share before you save anything. The difference between a small PC that works and one that nags you weekly is four decisions made once.

Decision one: the hibernation file

It is sized against your RAM and exists whether or not you hibernate. On a small drive it is the single largest easy reclaim, and the trade is Fast Startup, which is worth understanding before deciding.

Decision two: where user folders live

Documents, Pictures, Videos and Downloads can each be moved to another drive, and Windows supports it properly:

1. Open the folder's Properties.
2. Location tab, Move, choose a folder on the other drive.
3. Apply, and let Windows move the contents.
4. Repeat per folder. Downloads and Videos are usually the two that matter.

This is a supported relocation rather than a symlink hack, and applications follow it because they ask Windows where those folders are.

Decision three: stop syncing everything

OneDrive keeps local copies of whatever you open, and on a small drive that accumulates. Turning on files on demand and freeing up space for folders you rarely touch converts a permanent cost into an on demand one, which is how placeholders work.

Decision four: games and large software elsewhere

Steam supports a library on a second drive, and most launchers support an install location per game. On a machine with a small SSD and a large hard drive, that single setting is worth more than every cleanup on this site.

The maintenance that is actually needed

• Turn on Storage Sense for temporary files and the Recycle Bin.
• Clear Downloads, which fills quietly.
• Remove Windows.old after an upgrade rather than waiting ten days.
• Check the three folders that grow fastest for you, which are different per person.
