System Daquan teaches you how to clean up the U disk file can not be deleted, DOS help you solve

The files in the U disk cannot be deleted. I believe everyone has heard of the method of deleting files under DOS. Do you know how to do this? Do you know the DOS related file deletion command parameters? I will summarize it for you now. Delete one or several files: DEL [/P] [/F] [/S] [/Q] [/A[[:]attributes]] names

or ERASE [/P] [/F ] [/S] [/Q] [/A[[:]attributes]] names where names specifies one or several files or directory listings, ie the path and file name of the file. Wildcards can be used to delete multiple files. If a directory is specified, all files in the directory will be deleted. /P Prompt for confirmation before deleting each file. /F Forces the deletion of read-only files. /S Removes the specified file from all subdirectories. /Q Quiet mode. No confirmation is required when deleting global wildcards. /A Select the file to delete based on the attribute. Attributes R Read-only file S System file H Hidden file A Archive file - Indicates the prefix of "No", for example, in DOS, the current prompt is H:, directly enter del help.txt, then delete the current directory A file called help.txt. If you want to delete a file named help.txt in the temp subdirectory under the C directory of the C drive, the command format is: del c:\\windows\\temp\\help.txt
