Over time, your computer’s hard drive can become cluttered with unnecessary files and programs, causing your system to slow down and take longer to perform basic tasks. This can be especially true for the C drive, the primary storage location for the operating system and other essential files. Freeing up disk space and cleaning your C drive periodically is essential to maintain optimal performance.

A new disk cleaner that automatically finds junk files, allowing users to delete data and free up disk space without worrying about deleting something important.

4. Clean Temporary Files

While Windows Disk Cleanup software can be helpful, it has limitations. It doesn’t clear temporary files other applications use, such as the caches created by Firefox or Chrome browsers. These caches can take up gigabytes of disk space and aren’t cleared by Disk Cleanup. Browser caches use hard disk space to speed up the loading of websites, but for those who need more disk space immediately, this is not helpful.

If System Restore takes up a significant amount of hard drive space with restore points, it’s possible to reduce the allocated space.

If you don’t consider these features essential and require more disk space, you can free up several gigabytes by reducing the space allocated to System Restore.

7. Atomic Options

These tricks will certainly save a little space, but they will disable important Windows attributes. We do not recommend using some of these, but if you desperately need to free up disk space, then they could help:

Disable Hibernation — When you hibernate your System, it saves its RAM’s contents for your hard drive. This enables it to store its system state with no power use — the next time you boot your computer, you will be right back where you left off. Windows saves the contents of your RAM from the C:\hiberfil.sys file. To save hard drive space, you can disable hibernate entirely, which removes the document.

Disable System Restore — If diminishing the quantity of space System Restore uses is not significant enough for you. You can disable System Restore entirely. You’ll be out-luck if you need to use System Restore to restore your System to an earlier state; therefore, be warned.


In conclusion, maintaining sufficient disk space and keeping your C drive clean is crucial for optimal computer performance. By utilizing various tools and techniques such as disk cleanup, duplicate file finders, uninstalling unnecessary programs, and reducing the amount of space allocated to System Restore, you can free up valuable disk space and keep your system running smoothly. It’s essential to exercise caution when deleting files and ensure that critical system files are not removed. With these tips, you can keep your C drive organized and optimized for efficient operation.
