How to remove and delete temporary files. Free up storage space and improve computer speed. Mac and Windows.

Let those temporary files go.

Over time, they quietly pile up, taking over valuable storage space and limiting the memory your computer needs to run at its best.

If you're running low on space, it's a good idea to clear out those temp files—freeing up room for what truly matters. Whether you delete a few or wipe them all, the steps will vary depending on your laptop’s make and model.

How to:

Locating temporary files on a PC

Most programs will create temp files in a folder called C:\Users\AppData\Local\Temp — that’s likely where your computer stores most of your temporary files. It’s safe to empty out the Temp folder and delete the temp files you find there.

The best option to automate this process is to set up Storage Sense on your PC:

1. Type storage into search bar next to your Start button.
2. Select Storage settings.
   
   
   
    
3. Confirm that Storage Sense is on.
   
   
4. You can also configure storage sense to run at specific times and to empty your recycle bin on a schedule.
   
   

Temporary files on a Mac

Similar to clearing your browser cache, Mac refers to deleting temporary files as “clearing the cache” on your device.

There are two kinds of cache: system cache and application cache. In general, you should not delete system cache files. Application cache, sometimes referred to as the user cache, includes data associated with your apps that is saved so that it doesn’t have to be loaded every time you use an application. This allows your applications to work faster.

For example, if you work with high-resolution images or large video files, your computer could be storing a lot of app data related to the edits you make before you save the updated files. If you no longer use a specific app, you will want to delete its temporary files.

There is a third kind of cached data that is the result of sandboxing between apps but that data is automatically removed when you restart your Mac.

In macOS Monterey and older you can click on the Apple in the menu at the top of your screen and go to About This Mac > Storage.

If you are using macOS Ventura, this process has changed. You can still access the information via About This Mac > More Info, but this takes you to System Settings where you go to General > Storage > Storage Settings.

In Storage Settings, you will see a breakdown of Mac storage, which indicates where there are files that you might want to delete or move to cloud storage, such as OneDrive, in order to free up space.
