Methods to free up disk space on your Mac Catalina

You should check your storage usage regularly to allow space for important security updates and to speed up your Mac. If your disk is getting full, this will cause your Mac to run slower and restrict you from adding more files to your disk. Luckily, there are many ways you can free up space on Mac:

  1. Empty trash folder
  2. Delete unwanted files from the Downloads folder
  3. Remove applications’ junk files
  4. Clean duplicates
  5. Clean up caches from your MacBook
  6. Delete useless applications
  7. Use cloud drives
  8. Use the Storage Optimizer on macOS Catalina
  9. Use third-party apps

1. Empty trash folder

Your trash folder keeps deleted files in case you want to restore them at a later date. This is a great safety net in case you accidentally delete something. However, if you don’t empty this regularly, deleted files can take up lots of space on your Mac.

 

To empty your trash on macOS Catalina:

  1. To open your Trash, click on the trash can icon on the right-hand side of your dock. If the Trash icon shows that it’s empty, this means that there are currently no files in your Trash.
  2. When inside the Trash window, click the Empty button to delete all files currently in your Trash. This will then open a pop-up asking you to confirm if you’d really like to empty it. Click Empty Trash, and all files in your trash folder will be permanently deleted.
To open the Trash window on MacOS Catalina, click on the Trash icon on the right-hand side of your Dock.
Step 1. Click the Trash icon in your Dock
To empty your Trash on MacOS Catalina, when inside the Trash window, click on Empty in the top right corner.
Step 2. To empty the Trash, click Empty in the top right corner

You can also restore items in your trash or delete individual files. To find out how, please see our other piece on how to empty the Trash on a Mac.

2. Delete unwanted files from the Downloads folder

Unless you specifically change the settings to prevent it, your Mac will automatically put all downloaded files into the Downloads folder. This is an important place to look if you want to free up storage, as often, the largest files on your Mac will be located here, and you’ll need to delete your downloads consciously.

 

Here’s how to delete files from the Downloads folder:

  1. To find the Downloads folder, open Finder and select Downloads from the sidebar.
  2. Go to View in the top toolbar, select Sort by, and choose Size. This will order all your downloads by file size, so you can see what files are using up lots of disk space.
  3. Once you’ve identified some large files that you can get rid of, right-click on them and select Move to Trash. Alternatively, you can drag and drop the file into the trash can in your dock.
To find your Downloads folder on MacOS Catalina, open Finder and select the Downloads folder from the sidebar.
Step 1. Open Finder and select the Downloads folder from the sidebar
To sort files by size on MacOS Catalina, open Finder, and then hover over View in the toolbar. Go to Sort By in this menu, and select Size.
Step 2. Go to View, hover over Sort By, then select Size

As mentioned above, you’ll need to empty your trash after you delete items from the download folder. Otherwise, this process won’t be complete, and you won’t free up space on Mac Catalina.

3. Remove applications’ junk files

As you install applications, each app will create a cache for itself to help the app load faster. Unfortunately, these caches also take up space, and in some cases, even uninstalled applications continue to take up disk space with junk cache files. If you regularly clean junk files, you’ll free up your storage and speed up your Mac.

 

To remove applications’ junk:

  1. Click on your Mac desktop or a Finder window.
  2. In the menu bar at the top, click Go.
  3. Hold down the Option key. Select the Library folder once it appears.
  4. Navigate to the Library > Caches.
  5. Click the spyglass in the top right corner of your finder window and search for a recently uninstalled app within the Library folder.
  6. Select the relevant items, right-click on them, and press Move to Trash.
To remove applications’ junk files, you need to find the Go menu on your Catalina Mac. To do this, open Finder and click on Go in the toolbar at the top.
Step 1. In Finder, click on Go in the menu bar
To find your Library on macOS Catalina, when inside the Go menu, hold down the Options key on your keyboard. As you do this, click on Library once it appears.
Step 2. Hold down the Options > click on Library once it appears
To delete Caches on MacOS Catalina, once you're in your Library folder, navigate to Library > Caches. Here, you can delete files to clear your cache.
Step 3. Navigate to the Library > Caches folder > delete the unnecessary files

4. Clean duplicates

Often, your Mac’s precious storage space can be wasted by using duplicate files. Maybe you take 10 to 15 photos at a time with the intention to only keep one, or re-download the same menu from your favorite restaurant. We all end up accidentally hoarding useless files, but the good news is it’s really easy to get rid of duplicates.

 

One of the best ways to clean duplicates with just a few clicks is by using MacKeeper’s Duplicate Finder:

  1. Open MacKeeper, and select Duplicates Finder from the sidebar.
  2. Click Start Scan to find all the duplicate files on your Mac.
  3. Select the items you’d like to delete (e.g. photos).
  4. Click on Remove Selected to automatically delete duplicate files.
To delete duplicate files on macOS Catalina, open MacKeeper and select Duplicates Finder in the sidebar, then click Start Scan.
Step 1. Click on Duplicates Finder, then select Start Scan
To delete duplicate files on macOS Catalina in MacKeeper, select the duplicate file types you'd like to delete, and then click Remove Selected.
Step 2. Select the duplicate files you’d like to delete, then click Remove Selected

5. Clean up caches from your MacBook

Your Mac and its apps will automatically create caches, which allows them to launch quicker. However, cache files can quickly take up increasing amounts of space, so it’s important to clear cache every once in a while to clean up space on your Catalina Mac.

 

The step-by-step instructions to clear your cache are below:

  1. Open Finder and hit the Shift + Command + G keys on your keyboard, which will display Go to Folder.
  2. Enter the following text into the newly opened text box: ~/Library/Caches. Once you’ve entered the text, hit Go.
  3. Select the desired files you’d like to delete and drag them into the Trash can in your dock.
To clean up the cache, open Go to Folder on MacOS Catalina by navigating to Finder and pressing the Shift + Command + G keys on your keyboard at the same time.
Step 1. Open Finder and hit Shift + Command + G to display Go to Folder
To find your Caches folder on macOS Catalina, once you've opened Go to Folder, type in ~/Library/Caches. You can then move your unwanted files to the Trash.
Step 2. Type in ~/Library/Caches > hit Go > move cache files to Trash

6. Delete useless applications

We have all installed apps that have only been used once and never touched again—I’m looking at you, Audacity. Fortunately, it’s really simple and easy to delete unused applications and, this way, clear disk space on Mac Catalina. Here’s how:

  1. Open Finder and click on Applications in the sidebar.
  2. Select the application you want to delete, and drag it to the Trash can in your dock.
  3. Be sure to empty your Trash to actually delete the item and free up space.
To find your useless applications on macOS Catalina, open Finder. Then, click on Applications in the sidebar, and drag any unused apps to your Trash.
Open Finder > Applications > move your unwanted apps to Trash

7. Use cloud drives

These days, each of you has thousands of photos that take up lots of space on your Apple device. But as each photo is a memory, most of us are reluctant to delete them forever. Fortunately, there are cloud drives, which are great ways to preserve your memories while simultaneously freeing up disk space. Cloud drives like iCloud work by uploading your files to the internet, meaning that as long as you’re online, you can always access your files.

 

To shift your files to a cloud drive on Mac:

  1. Open Finder and click on iCloud drive.
  2. With this window open, simply drag and drop the files you wish to upload into your iCloud.
  3. To free up space, once the file has been uploaded, delete the copy of the file on your laptop and empty the Trash.
To find your iCloud Drive on macOS Catalina, open up Finder and navigate to iCloud Drive in the sidebar. This will then open your iCloud.
Step 1. Open Finder and select iCloud Drive from the sidebar
To upload files to your iCloud Drive on macOS Catalina, drag and drop the files you wish to back up into your iCloud Drive folder.
Step 2. Drag and drop the files you wish to upload to your iCloud Drive folder

8. Use the Storage Optimizer on macOS Catalina

If, like me, you enjoy watching movies and TV on your Mac, use the Storage Optimizer on Mac Catalina to remove the ones already watched:

  1. Press the Command + Spacebar keys on your Mac to open the Spotlight search.
  2. Type in Storage Management and hit Enter.
  3. Click the Optimize… button and let your computer do all the work.
To use the Storage Optimizer, open Spotlight Search on macOS Catalina,  then press the Command + Spacebar buttons on your keyboard at the same time.
Step 1. Hit command + spacebar to open Spotlight Search
To locate Storage Management on macOS Catalina, open Spotlight Search, and type in Storage Management into the search bar, then hit Enter.
Step 2. Type Storage Management into the Spotlight Search bar
On macOS Catalina, in the Storage Management menu, click the Optimize button, and your Mac will automatically delete movies and TV shows you've already watched.
Step 3. In Storage Management, click Optimize

No secret, video files take up so much disk space on your Mac, with the built-in Storage Optimizer, you can automatically delete movies and TV shows you’ve already watched without needing to find the files manually. Don’t worry, these files can always be re-downloaded if you want to rewatch your favorites.

9. Use third-party apps

Wouldn’t it be a breath of fresh air if an app could clear up disk space automatically on your Catalina Mac? Fortunately, you’re in the right place. MacKeeper’s Safe Cleanup can look through all of your files and find out what is taking up lots of storage space on your device so you can delete them. Try it yourself:

  1. Open the MacKeeper app and select Safe Cleanup from the sidebar.
  2. Select the relevant items you’d like to delete (e.g. Caches).
  3. Click Clean Junk Files and let MacKeeper do all the work.
