dos file deletion del command
Updated: April 27, 2009 18:24:59 Author:
The command used to delete a file is del, and its full name is delete.
The usage of the del command is very simple, just use the "del file path" format. For example, if you want to delete the root directory of the D disk, just use del d:\.
However, not all files can be handled with just the del command, such as files with hidden attributes, read-only attributes or system attributes. If d:\ has hidden attributes, if it is just del d:\, d:\ will remain unmoved. How to delete it? At this time, you need to add some auxiliary parameters to the del. The hidden attribute is hidden, use del /a:h, the read-only attribute is read, use del /a:r, the system attribute is system, use del /a:s, if you don't know what attributes the file is, then use del /a - but there is an exception. When the file has read-only attributes, you have to add the del /a /f parameter. Therefore, if you want to force delete a file that does not know the attributes, using the del /a /f statement is the safest way. Here, the /f parameter means force deletion of read-only attribute files, and f is taken from force, which means force.
For a while, the Viking virus raged the Internet and destroyed many files with a destruction. The most important point is that a file was generated in each directory. As long as these files were deleted, the virus would be no longer harmful. To delete files in each directory, it will be annoying if you click on the subfolders to delete them. If you use the del command, a simple statement can be done, that is: execute the del /a /f /s command in the specified directory. Here, /s means searching all subfolders in the current directory and deleting the specified file. S is taken from sub, indicating the meaning of "sub-directory" and "sub-directory".
Deleting files is a very dangerous thing. If you are not careful, you may delete important files. Therefore, you need to be careful when performing the deletion operation. If you need to confirm before deletion, you can add a parameter: /p.
Of course, for very confident deletion operations, there is no need to confirm one by one. You can choose the silent deletion mode. At this time, you need to use the parameter: /q, which is the abbreviation of quiet.
