While working on old PCs, and not only at a certain stage, the question of how to clean drive C from unnecessary files may become very relevant. Although the sizes of hard drives are now measured in terabytes, still the availability of free space is important. The haphazard accumulation of data and information ultimately leads to the fact that most users are faced with this problem. There are three ways to solve it: built-in utilities, third-party software, and their combination. The latter method is the most practical. It is also possible to partially overcome this situation with the help of manual operations: copying and deleting. Each of these methods can achieve a positive result when you need to clean drive C from unnecessary files.
Handmade
Ever since the old MS-DOS operating system, users have had to periodically clean up disk space by removing unnecessary information. To do this, both OS commands and file managers (for example, Norton Commander) were used. This method is still relevant today. Now we will figure out how to clean the disk of files in modern Microsoft operating systems in this way. It is applicable to the “Desktop”, “My Pictures”, “My Documents”, “My Records” folders and the “Temp” system directory. It is better to copy all the contents except the shortcuts from the first four elements to another logical drive, for example, D. To do this, just hold down the Ctrl key and without releasing it, step by step, press the left mouse button on each icon that needs to be moved. Then open another logical volume and select the "Paste" command. To better organize the information, you can create a catalog and move the data into it already. To open the "Temp" folder, immediately click the combination of Win and R. The "Run" window will open. In it, enter the command "temp" and click "OK." After opening the folder, press the combination of Ctrl and A. After

Select all the contents, press Del and, without releasing it, Shift. We respond to the request that appears positively by clicking "OK." On this stage is over.
Embedded Tools
Now we will figure out how to clean drive C from unnecessary files using the built-in utilities. To do this, just open the "My Computer" window, on the icon of the system partition, call the context menu by right-clicking. In it, select the item "Properties". In the window that opens, on the "General" tab, there will be a "Disk Cleanup" button. After clicking on it with the left mouse button, the corresponding window will open. In it, select the necessary items by checking the boxes.
Additionally
For this operation, you can use third-party programs that,
unlike built-in tools, they have more functionality and capabilities. An example is the CCleaner application. With it, you can not only solve the problem of how to clean drive C from unnecessary files, but also fix important errors in the OS registry. To remove unnecessary system information, you need to go to the “Cleaning” tab, do “Analysis” immediately, and then uninstall the data.
Final recommendations
In order not to have a problem with how to clean drive C from unnecessary files, it is best to periodically perform preventive maintenance in all three ways that were previously outlined. This will not only control the amount of free space on the drive, but also prevent various problems that may arise in the future.
