How to Free Up Space on the C Drive<\/h2>\n
Follow the solutions below to clear space on the C drive. Go through the steps, starting from the simplest:<\/p>\n
Method 1: Use good third-party software<\/h3>\n
It is not a secret that the easiest, fastest, and most convenient way to clean up your disk space is by using third-party software. There are many options available on the market, such as CCleaner <\/a>, Advanced SystemCare <\/a>, or Iolo System Mechanic <\/a>. In fact, we have conducted a comprehensive overview of different PC cleaners<\/a>.<\/p>\nTheir key advantage is maximum automation and speed in the cleaning process. One of the best programs for freeing up space on your C drive is Auslogics BoostSpeed<\/a>. It\u2019s an all-in-one utility designed to clean, speed up, and generally make your computer perform better.<\/p>\nIn terms of clearing space on your C drive, BoostSpeed has several tools, depending on what you want to delete.\u00a0 In other words, you don\u2019t have to install separate tools for specific tasks, like when you want to delete duplicate files or temporary files.<\/p>\n
Here\u2019s how to use the tool to get more storage on your C drive:<\/p>\n
\n- Go to the Auslogics official site, download the software <\/a>, and install it.<\/li>\n
- Open the program and click on My Tools<\/em> to open all the resources available to you.<\/li>\n<\/ul>\n\r\n \r\n
![\"Open]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\n- Scroll down to search for Deep Disk Cleaner <\/em> and click on it.<\/li>\n<\/ul>\n\r\n \r\n
![\"Scroll]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\n- Then, click on Scan Now <\/i> after ticking the files you want to scan.<\/li>\n<\/ul>\n\r\n \r\n
![\"Click]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\r\n\tNote<\/div>\r\n\tThe tool performs deep disk scans for all kinds of junk files, temporary files<\/a>, system files, old backup files, and other clutter that stores up over time. <\/div>\r\n<\/div>\n\n- After the scan is completed, select the files you wish to delete and click Clean up. <\/i><\/li>\n<\/ul>\n\r\n \r\n
![\"After]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nBesides removing clutter from your system, you can also delete duplicate files and photos<\/a>, Windows updates, and unused applications.<\/p>\n\r\n\tPRO TIP<\/div>\r\n For example, if you want to uninstall programs and apps, go back to All Tools and click on Uninstall Manager. From there, you can select all the applications you want to delete and click Uninstall.<\/p>\nThis will completely remove unnecessary apps and programs, including all leftovers that usually remain when uninstalling with Windows tools. Additionally, Auslogics BoostSpeed<\/a> allows you to force uninstall any program you can\u2019t delete using normal methods like Control Panel.<\/div>\r\n \r\n Download for Free<\/a>\r\n Learn More<\/a>\r\n <\/div>\r\n<\/div>\r\n\nSo, as I have mentioned, a third-party app is a convenient solution for cleaning your computer. However, there are also built-in methods that can help clean your C drive.<\/p>\n
Let\u2019s now talk about them.<\/p>\n
Method 2: Run Disk Cleanup<\/h3>\n
Disk Cleanup is a built-in tool in Windows designed to remove unnecessary files from your drives.<\/p>\n
\r\n\tWe have a detailed guide on how to use Disk Cleanup<\/a>. That\u2019s why here, we will just cover the basic steps to remove some initial clutter. Be sure to check out the full article! <\/div>\r\n<\/div>\nFor example, with Disk Cleanup, you can free up space by deleting temporary files (both internet and Windows), Recycle Bin files, system files, and thumbnails.<\/p>\n
Here\u2019s how to free up space on the C drive on Windows 10 and 11 using Disk Cleanup:<\/p>\n
\n- Go to File Explorer.<\/li>\n
- Click This PC <\/i>, right-click on your primary drive (usually, it\u2019s the C <\/i> drive), and select Properties<\/i>.<\/li>\n
- Then, select Disk Cleanup<\/i>.<\/li>\n
- Click Clean up system files<\/i> and check the items you want to delete.<\/li>\n<\/ul>\n
We can\u2019t fail to mention one more built-in Windows method to manage C drive space: Storage Sense. It helps remove temporary files, files in the Recycle Bin, files in the Downloads folder, old Windows update files, and system error memory dump files.<\/p>\n
While Disk Cleanup requires user input for each session, Storage Sense automates the process. So, consider using Disk Cleanup for immediate analysis and cleaning, while Storage Sense is a great option for scheduled maintenance<\/a>.<\/p>\nHere is a simple comparison showing why a third-party tool is more efficient than Windows built-in tools for cleaning your C drive:<\/p>\n
