C Drive Cache and Temp Cleanup Guide

Caches and temp files are the easiest wins—“delete aggressively where safe, spare what’s storage-sensitive.”

Must-clean

• %TEMP%, C:\Windows\Temp, and app crash dumps.
• Update cache SoftwareDistribution\Download (stop services first).
• Large logs: C:\Windows\Logs\CBS and third-party crash logs.

Optional-clean

• Browser cache: keep logins for common sites; you can clear images/files only.
• WeChat/Steam/Adobe caches: clear via settings, don’t touch config files.
• Video/recordings: offload as soon as the project ends.

Cadence

Set a monthly reminder or use Storage Sense; reboot after each cleanup for stability. If space is tight, shorten to every two weeks.

Frequency tips

• Office PC: monthly.
• Gaming/video rigs: every two weeks; move media when done.

Lazy approach

Pin %TEMP% and C:\Windows\Temp to Quick Access for one-click habit building.

Backup script

Script idea: zip %TEMP% and C:\Windows\Temp to D: first, then delete originals—if you over-clean, unzip to restore.
