How to clear an application's cache on Windows or Mac
Jul 29, 2025 am 01:22 AMTo clear the application cache to resolve slow or abnormal problems, manually delete temporary files in the system. Windows users can enter %localappdata% through Win R to open the local cache directory, find folders such as Temp, Cache or program names and delete their contents; some software such as browsers also provide built-in cleaning functions. Mac users can open Finder, go to the ~/Library/Caches/ directory, and find the corresponding application cache folder to delete it, but avoid deleting the system cache starting with com.apple. When cleaning, the corresponding program should be closed to avoid accidentally deleting important files. The more frequent the cleaning, the better. It is recommended to process it regularly once a month.
Clearing the cache of your application is an easy and effective way to resolve slow or abnormal software running. If you find an app stuttering, loading fails, or having strange problems after updates, cleaning up the cache is usually a good attempt.

How to clear program cache on Windows
Applications on Windows systems will store temporary files and cached data in specific locations. You can manually find these files and delete them.

-
Common path :
C:\Users\你的用戶名\AppData\Local
There are many cache directories left by programs in this folder, such as the cache of Chrome browser is in
Google\Chrome\User Data\Default\Cache
. -
Operation suggestions :
- Press
Win R
to enter%localappdata%
to open the local cache directory. - Find the corresponding folder according to the software name you are using, such as
Temp
,Cache
or program name. - Just delete the contents in these folders (it is not recommended to delete the entire AppData directly, as important configurations may be deleted by mistake).
- Press
Some programs also provide built-in cleaning functions, such as the browser usually has the option of "Clear browsing data", and you can directly check the cache to clean it.
How to clean application cache on Mac
Mac design focuses more on privacy and clear structure, and cache files are generally placed in hidden folders under the user directory.
-
Cache path :
~/Library/Caches/
There are cached data for various applications, such as Safari, WeChat, QQ, etc.
-
Opening method :
- Open Finder and click "Go to Folder" in the top menu bar
- Enter
~/Library/Caches/
and then enter - Find the corresponding folder of the application you want to clean and delete it directly
Note: Do not delete the system cache starting with com.apple
unless you know what you are doing.
Some third-party tools such as CleanMyMac can also help you clean up caches in batches, but manual operations are actually not complicated. The key is safety and controllability.
Things to note when cleaning cache
- Don't delete folders you don't know : There may be some content in the cache directory that is unfamiliar but is very important for the operation of the system or program.
- Close the corresponding program and clean it up : If you delete the cache while running the program, you will sometimes be prompted "The file is in use".
- The less cache, the better : some programs rely on cache to increase loading speed, and frequent cleaning will affect the experience.
- Regular cleaning is more useful : it can be cleaned up once a month instead of daily cleaning.
Basically these are the methods. Different systems have slightly different ideas, but the idea is similar: find the cache location and delete it in a targeted manner. Not complicated but easy to ignore.
