In Windows 7, "files cannot be displayed as thumbnails "? Check the available space of the System Disk

Recently, a problem occurs on Windows 7 on my computer: thumbnails cannot be displayed in image files, but Icons can only be displayed.

Google has related information on the Internet, such:

How to solve the problem that files cannot be displayed with thumbnails-yibaodian

Right:

 

Folder and search options-View-"Always show icon, never show thumbnail" and "show file icon in thumbnail form"

Performance option-visual effect-"display thumbnails instead of icons"

 

Check and repair, but no effect.

Remember that some system patches were installed before the fault occurred! Check that the available space of the system disk C is more than 300 mb. The available space should be more than 1 GB! Will it be caused by a small amount of available space on the system disk?

Using QQ Computer Manager to clean up junk files is limited!

Or manually clean up. c: \ Users \ <username> \ appdata can be cleaned up many times. There are so many QQ files left. I really don't know how QQ Computer Manager cleans up the files ......

After cleaning, the available space of disk C is restored to more than 1 GB! The thumbnail is displayed again in the image file!
