Examples:

MD \A\B\C\D          – Create a directory tree

DIR \always.mp3 /s   – Finds files (ex. always.mp3) by looking
                       first in the root directory and then
                     – search all sub-directories

DIR \ /ah            – Show system/hidden files in root directory

RD /s /q *.*         – Remove all except system/hidden files

CD ..                – Take you to the parent directory

CD /d F:\Homework    – Change drive & directory at the same time

SUBST B: F:\Data     – Create virtual drive B: which is F:\Data

SUBST H: F:\Homework – Create virtual H: which is F:\Homework

SUBST B: /d          – Delete virtual drive B:

SUBST H: /d          – Delete virtual drive H:

ATTRIB /d            – set attributes for Directories too

ATTRIB +a *.* /s     – set archive bit for directory and all
                       sub-directories (see XCOPY /semi *.* d:\)

XCOPY *.* D:       ~ Copy all files to the D: directory

XCOPY /SEMI *.* D: ~ Copy all files in all subdirectories (/S); 
                     including all empty directories (/E); 
                     copy only files with the archive bit set 
                     on and turn it off when finished (/M);
                     and the target is always a directory (/I)

 XCOPY *.* F:\donkey /SHREK

       /S ~ copy all Subdirectories
       /H ~ show/copy Hidden files
       /R ~ will overwrite Read-only files
       /E ~ copy Empty files
       /K ~ Keep all existing attributes
