Part 4. Manually Clear Files to Free Space on Startup Disk
If you prefer to clear files manually, no problem, I can give you tips on where to start and the quickest ways to do it. Let’s begin from the files consuming a lot of spaces.
Clean the Downloads Folder
Downloads folder may be one of the less important folders in your Mac but this performs a great responsibility.
It saves all the files such as documents, apps, photos, videos, and many more since this is where all these files are stored by default. Luckily, you can clean the Downloads folder easily!
- Go to Finder and select Downloads among the listed files on the left pane
- Highlight all or selected files and press Delete
Well, we are all guilty of hoarding lots of movies into our computers and little do we give importance to them once we are done watching. However, they are also culprits of consuming a lot of space in the system.
Delete the old movies you have saved to free some space.
- On the same Finder window, click on Movies
- Find and highlight those movies you have already watched or no longer needed
- Press Delete
You can also do the same thing on the Desktop Folder, Documents, Music, and Pictures. After you have manually gone over these folders, don’t forget to Empty the Trash.
- Click and hold the Trash icon from the Dock
- Hold and click on Empty Trash
If in any case, you have sensitive information that you want to delete, you can choose to secure empty the trash folder.
- Click and hold down Trashcan icon from the Dock
- Hold the command key and click on the Trash. You will notice that Empty Trash will change to Secure Empty Trash. Click on it. This might take a while to complete its process
Another option is to do it from any open Finder window by clicking on the Finder menu and click Secure Empty Trash.
But, the biggest space-eater of all is the duplicates. Yup! Those files you might have saved on different file name or location can also clog up the system.
What you can do to quickly remove the duplicates is to use the same program I recommended, PowerMyMac. Click here to download and install it on your Mac now! You don’t have to search for the duplicates which can take much of your time and efforts.
