When you are running out of space on your Windows 7 or Windows 10 system's C drive, it is crucial to know which files can be deleted to free up space. However, improper deletion may affect the stability of the system. Here are five C drive folders and their files that can be safely cleaned up, along with the precautions.
1. LogFile folder
位置： C:\Windows\system32\logfiles
Description: The LogFile folder contains log files for system and software runs. These logs are usually of no practical use to the average user and can be safely deleted. But please be careful to delete only the contents of the folder, not the LogFile folder itself!!
2. Temp folder
Location: C:\Windows\Temp
NOTE: The Temp folder stores temporary files and caches generated by the system and software runtime. These files take up a lot of space on the C drive and can be deleted. Again, only delete the files and subfolders inside the folder, leaving the Temp folder.
3. Prefetch 文件夹
位置： C:\Windows\Prefetch
NOTE: The Prefetch folder contains the read-ahead files that are generated when the Windows system accesses the application. These files can take up quite a lot of space and can be deleted. Please delete only the files in the folder and keep the Prefetch folder.
4. Backup 文件夹
Location: C:\Windows\winsxs\backup
Note: The Backup folder contains the temporary backup files generated during the running of the software. These files can be deleted when the software is saved normally and exited. It is important to keep the Backup folder and only delete its contents.
5. Help folder
Location: C:\Windows\Help
Note: The Help folder contains system help files. While these files usually don't take up much space, they can be deleted if needed. Only the files and subfolders within the folder are deleted, leaving the Help folder itself.

Notes:
- If you used a third-party tool to move these folders to a different partition, clean them up in a new location.
- If you have recently cleaned the C drive, these folders may not be large and can be cleaned up later.
- Please check carefully when deleting to avoid accidental deletion of other important system files.
By cleaning the above folders regularly, you can effectively manage the space of your C drive and optimize the performance of your system. Remember to double-check before deleting to avoid accidentally deleting important files.
