General knowledge about commands

In this page, we’re going to offer you solutions to remove viruses from your USB drive, memory card, in fact, any drive in a Windows 10 computer using CMD. In order to remove a virus using CMD, we will use a famous CMD command called ‘attrib’ command. So first, we’d better have some understanding about the commands we’re supposed to use.
Here are the basic attributes of the ‘attrib’ command which we will use later:
R – R represents the “Read-only” attribute of a file or folder. Read-only means the file cannot be written or executed.
H – H stands for the “Hidden” attribute.
– Similarily,  A stands for “Archiving” which prepares a file for archiving.
– S attribute changes the selected files or folders into a system file from a user file by assigning the “System” attribute to that particular file.

“attrib” Syntax:

ATTRIB [+ attribute | – attribute] [pathname] [/S [/D]]
In the above command, let’s see what the different parameters and switches are:
‘+ / –’:            To enact or to cancel the specified attribute.
‘attribute’:   As explained above.
‘/S’:                  Searching throughout the entire path including subfolders.
‘/D’:                 Include any process folder.
‘pathname’: Path where the target file or folder is located.

Here is the proper syntax for attrib command:

ATTRIB [+R | -R] [+A | -A ] [+S | -S] [+H | -H] [+I | -I] [drive:][path][filename] [/S [/D] [/L]]
