Clearing System Cache and Temp Files
Does your computer feel slower than usual? Is it freezing more often or taking too long to load basic programs? One common cause of these issues is built-up system cache and temporary files. These files are meant to be temporary but often hang around, clogging up your computer and affecting performance over time.
The good news? Clearing your system cache and temp files is easy, safe, and a great way to refresh your PC or laptop. This guide is written specifically for home users on the Central Coast and includes step-by-step instructions for Windows and Mac, plus info on when to call Zelrose IT for a professional clean-up.
What Are Cache and Temp Files?
Cache files are small files stored by your system and programs to help load things faster in the future.
Temporary files (temp files) are created when programs are running, installing, or updating.
Over time, these files build up, causing:
Slower system performance
Freezing or crashing apps
Less available disk space
Benefits of Clearing Cache and Temp Files
Frees up valuable space
Reduces freezing and system lag
Speeds up startup and program load times
Prevents software conflicts during updates or installations
How to Clear Cache and Temp Files on Windows
1. Use Windows’ Built-in Disk Cleanup Tool
Click the Start Menu and type Disk Cleanup, then press Enter.
Select your main drive (usually C:) and click OK.
Tick the following boxes:
Temporary files
Thumbnails
Recycle Bin
Temporary Internet Files
Click OK, then Delete Files to confirm.
Optional: Click Clean up system files for deeper cleaning.
2. Manually Clear Temp Files
Press Windows + R on your keyboard.
Type %temp% and press Enter.
Select all files (Ctrl + A), then press Delete.
Some files may be in use - skip those when prompted.
Repeat the process with this command:
temp
(Just type it in Run box and delete files the same way.)
3. Use Storage Sense (Windows 10 & 11)
Go to Settings > System > Storage.
Toggle on Storage Sense to clean automatically.
Click “Configure Storage Sense or run it now” to fine-tune what gets deleted.
How to Clear Cache and Temp Files on Mac
1. Manually Clear User Cache
Open Finder and press Shift + Command + G.
Type ~/Library/Caches and press Enter.
Delete folders inside (but not the Caches folder itself).
Empty the Trash afterward.
2. Clear System Cache (Advanced Users)
From Finder, open Go > Go to Folder again.
Type /Library/Caches and press Enter.
Delete contents, but be careful - only remove items you’re confident are safe.
Tip: If you're unsure, Zelrose IT can safely clear system-level caches for you.
Trusted Tools for Easy Cleanup
If you'd prefer a guided tool, these are safe and widely recommended:

What Not to Delete
