When an Acer laptop reports that the drive is full, Microsoft's free-space guidance starts with Storage settings: it shows what is using space, offers Storage Sense to delete temporary files and the Recycle Bin contents, and lets you remove apps you no longer use. Acer has a knowledge-base article titled Free up disk space after upgrading to Windows 10, which covers the old Windows files left after an upgrade. Then move large personal files to a USB drive or cloud storage rather than deleting them, and check the Downloads folder and the Windows.old folder, which Storage settings can remove.
A gaming Acer with several large game installs fills the fastest, and free space matters beyond convenience: Windows needs room for updates and virtual memory, so a full drive makes the laptop slow and updates fail.

Before you touch a setting
Record this first — changing settings destroys the evidence

- What Settings, System, Storage lists as the largest categories
- Whether a Windows.old or large Downloads folder exists

Exact questions
Common questions
How often should I clean up?+
Turn on Storage Sense so temporary files clear on a schedule, and check Storage settings every few months, especially after big game or update installs.
Can I move my Downloads folder?+
Yes, to an external or second drive through the folder's Location tab. Keep a copy until you have checked the files open.
Should I use a cleaning app?+
Not needed. Storage Sense does the safe cleanup, and third-party cleaners can delete what you need or install extra software.
Where do old game and video files hide?+
In Downloads, the game launcher's library folder and the Videos folder. Storage settings lists them by size so you can decide what to move.

For files and games, yes. Move them with the app's own move option so Windows keeps working.

It deletes temporary files and Recycle Bin contents that Windows marks as safe, and can run automatically.
