Why C drive is running out of space
There could be many reasons, but the most common reasons include:
1. C drive shows full but it is not
It is a possible reason, but few people have such experience. Only one of my readers feedback such issue caused by virus, try to scan your disk with antivirus software if you think the disk space shows incorrectly.
2. C drive shows full but many folders seem empty
Many people feedback such experience: they try to check the files and folders in C drive and found many ’empty’ folders that occupied much disk space. In this situation, change the folder option to show hidden files.
In any folder of Windows Explorer, click Organize on top left corner and then click Folder and search options:
Switch to View tab, select ‘Show hidden files, folders, and drives’.
3. C drive is filling up with files
This is the most common reason why C drive becomes full. Windows Updates, 3rd-party programs and many other types of files write into C drive every day, of course it runs out of space sooner or later, no matter how big it is.

- Install new programs to another separate partition such as D.
- Change the default file output location to other large partitions, especially for the program for pictures, videos, games, projects, etc.
- Expand C drive as large as possible. If the hard disk is small, consider replace it with a larger one.
- Free up space with Windows 7 Disk Cleanup every month.
