DOS sets an attribute of "Archive" on any new or changed files. This is basically setting a tripwire to let the system know that the file must e cleared during the next backup.
Dos files are the files with the extension .bat which are used for programming in DOS. This is also called as batch file programming.
Hidden files are files stored on the disk, but which do not show up when you list a directory of the disk.In DOS, you normally type the command DIR to view the files on a disk. If you would like to see hidden file names, use the command DIR /AH (A=Attribute; H=Hidden).
There is no specific file extension for MS-DOS. Files can have any 3 character extension in MS-DOS.
To copy files to RAM in MS-DOS, you have to use the COPY function after converting the file to a system file with the *.sys extension.

In DOS, the file that typically executes other files is COMMAND.COM. This is the command-line interpreter for DOS, responsible for executing commands and running batch files. When a user types a command or script name at the prompt, COMMAND.COM processes the input and executes the corresponding executable, batch, or script file.
The copy command in MS-DOS is used to duplicate files from one location to another within the file system. It allows users to specify the source file and the destination, enabling efficient file management. Additionally, the command can be used to combine multiple files into one, such as merging text files. Overall, it serves as a fundamental tool for file manipulation in the MS-DOS environment.
