The operation cannot be completed because the file is opened by system
When you try to delete a file, you may receive the message “The operation cannot be completed because the file is open by system” and cannot be deleted.
To force this deletion, investigate with the openfiles command. (You must run the command prompt with administrator privileges.)
The ID will be displayed, so type the following in the net file command
net file id番号
The status of the file is displayed.
net file id番号 /close
The above command will unlock the process.
You can then physically delete the process and it will be removed.
