Long gone are the days when most of the people used to suffer from storage problems. With the advent of modern technology, hard drives can store tons of data. However, they always seem to fill up after a certain period – mostly the c-drive. Have you ever noticed the c-drive suddenly full on windows 7 even if you’ve not added any more data? Well, this issue mostly comes when using Windows 7 both 32-bit and 64-bit.

Why c-drive suddenly running out of space on Windows 7?

Before we get to the actual point, let’s discuss why the c-drive shows full after a certain period. Well, there can be several reasons. For instance, a faulty program that constantly makes copies of its files and occupy more than enough storage space.

However, a virus can also display incorrect information about the storage devices. For example, once my PC was showing “Low Disk Space” error even there was around 34GB free space on the disk. On the other hand, sometimes empty folders on the c-drive also occupy much disk space. Looking forward to a single solution to all these problems? Follow the article below.

6 Free Ways to Free Up Disk Space on Windows 7

Here are some steps you can take to free up disk space on your Windows 7 C drive:

  • Use Disk Cleanup: Windows has a built-in tool called Disk Cleanup that can help you find and delete unnecessary files. To use it, go to Start menu > All Programs > Accessories > System Tools > Disk Cleanup. Select the drive you want to clean up, and the tool will scan for temporary files, cached files, and other items that can be safely deleted.clean up disk c drive
  • Uninstall unused programs: Over time, you may have installed programs that you no longer need or use. To uninstall them, go to Control Panel > Programs and Features, select the program you want to remove, and click Uninstall.
  • Delete temporary files: Windows and many programs create temporary files that can take up a lot of space over time. To delete them, press the Windows key + R, type %temp% and hit Enter. This will take you to the folder containing temporary files. Select all files and delete them.
  • Move files to an external drive: If you have large files that you don't need to access frequently, such as videos or backups, consider moving them to an external hard drive or cloud storage service.
  • Disable hibernation: If you don't use hibernation, you can disable it to free up disk space. Open a command prompt with administrative privileges and type powercfg -h off and press Enter.powercfg
  • Disable system restore: System Restore can take up a lot of disk space, especially if you have multiple restore points. To disable it, right-click Computer, and go to System Properties -> Select c drive, continue -> Turn off system protection, and click OKdisable system restore

Extend C Drive with System Tool Disk Management

Note: Expanding c drive needs free adjacent unallocated space on c drive that you may need to delete the right side D volume for example.

First of all, you can try Windows system tool to extend C drive, just right-click “Computer”, choose “Manage” option, and enter “Disk Management” module, you can see all your partitions listed there.

If you have unallocated space at the right side of c drive, you can right click the C drive, choose “ Extend Volume” to go.

If you have no unalloceted space here, you will find the “Extend Volume” greyed out, you need to delete c drive next partition at first to get unallocated space, and then extend your system drive, but there may be data loss problems. So please backup data at first.

Note: Shrinking volume won't work since Disk Management cannot move unallocated space to c drive if there are inbetween volumes. Plus Disk Management cannot extend c drive if the c drive is FAT32 file system even with right side contiguous unallocated space available.
