DOS Commands, Wildcards, and Attributes

- DOS (Disk Operating System) Commands are system commands that are commonly used to accomplish common tasks such as moving, renaming, and deleting files. There's a wide variety of tasks that can be done with these commands.

Examples are:


  • mkdir : Make directory
  • move (insert file name here) : Moves a file
  • copy (insert file name here) : Copies a file
  • del / delete : Deletes a file
  • cd.. : Goes back 1 directory


- Wildcards in DOS consists of these characters, the asterisk (*) and question mark (?) . The asterisk represents more than 1 character, whereas the question mark is used to represent a single character. They are beneficial to a user in the DOS environment, because it allows the user to apply changes to more than one file at a time.


- Attributes in regards to files are settings that allows or disallows the user/operating system the right to access a file. The 4 attributes are :


  • Read Only: To “Read-Only” the selected files.
  • Hidden: Assigns the hidden attribute to selected files/folders.
  • Archiving: Prepares the selected folders/files for archiving.
  • System Change: Changes your selected files by assigning the system.

Preventive Maintenance Planning

Preventive maintenance is regularly performed tasks on equipment to prevent it from failing or breaking down unexpectedly in the future


Preventive Measures:


  1. Updates to the operating system and applications
  2. Updates to the anti-virus and other protective software
  3. Hard drive error checking
  4. Hard drive back up
  5. Hard drive fragmentation
  6. Device drive updates
  7. Firmware updates

Its important to remember to carry out these measures as frequently as you need to. For example backing up your hard drive/data and scanning for viruses should be done daily. Whereas cleaning internal parts such as the read and write heads on the platter only need to be done annually. Some parts in your PC are more delicate than others, and require more attention to make sure they are functioning properly. If these measures aren't taken care of within due time, it could be detrimental to your system.

- When an application or driver is installed


Access this feature by following this path:

Start > All programs > Accessories > System Restore
