To make "myfiletxt" a hidden system file in Windows, you can use the Command Prompt. The command is: attrib +h +s myfiletxt
. This command adds the hidden attribute (+h
) and the system attribute (+s
) to the file, making it hidden from normal view and designated as a system file.

System files are files the operating system needs to function (and they may be hidden). Hidden files are those files that are not displayed when you show a directory listing. A file can be both a system file and a hidden file, but a hidden file does not have to be a system file, nor does a system file need to be hidden.
ls -al list hidden file also.Hidden files starting with "."
The attrib command is a Recovery Console command used to change the file attributes for a file or directory while in Recovery Console. An attrib command is also available from the Command Prompt. attrib [+r|-r] [+s|-s] [+h|-h] [+c|-c] [filename] +r = This assigns the read-only file attribute to the file or directory. -r = This removes the read-only attribute. +s = This assigns the system file attribute to the file or directory. -s = This removes the system attribute. +h = This assigns the hidden file attribute to the file or directory. -h = This removes the hidden attribute. +c = This assigns the compressed file attribute to the file or directory. -c = This removes the compressed attribute. filename = This is the file or directory that you are wanting to change the attributes of.

"Hidden" is a file attribute; this is information about the file that shouldn't change when you reinstall the operating system.
The command "attrib +r -h" is used in the command prompt to set a file as read-only (+r) and remove the hidden attribute (-h) from a file. This command can help protect files from being accidentally modified and also make hidden files visible.
Attirb command is used to change the attribute of any file of directory. There are following kinds of attributes in DOS:R - Read OnlyH - HiddenA - ArchiveS - SystemAmong all, Archive (A) attributes applies by default as we create any file or directory. System (S) attribute is reserved for the System Files (IO.SYS, MSDOS.SYS, CONFIG.SYS) of MS-DOS. We can apply Read Only or Hidden attributes to any file or directory to make it read only of hidden. The syntax is as follows:To make file Read Only: attrib +r To make file Hidden: attrib +h To remove Read Only attribute: attrib -r To remove Hidden attribute: attrib -h Similarly we can set/remove Archive (A) or System (S) attributes to file with +a/-a or +s/-s option.
The hidden file attribute is a setting in file systems that allows files or directories to be marked as hidden, making them not visible in standard directory listings. This is often used to prevent accidental modification or deletion of system files or to keep certain files private. Users can still access hidden files by changing settings in the file explorer or using specific commands in command-line interfaces. The attribute is commonly found in operating systems like Windows, Linux, and macOS.
To lock a file in DOS, you can use the ATTRIB command to set the file as read-only, which prevents modifications. The command syntax is ATTRIB +R filename, where "filename" is the name of the file you want to lock. Additionally, you can set file permissions using attributes like hidden or system. However, true file locking in DOS is limited, as it doesn't provide robust file locking mechanisms like modern operating systems.
