ITSC 1405 – Exam #2 Study Notes Page 2 of 3 Examples:

 DIR \always.mp3 /s – finds (searches for) files by looking first in the root directory, and then searching all subdirectories

 DIR /AH \ – shows system and Hidden files in root directory

 RD /S /Q *.* - will removed everything except system and hidden files

 CD .. – takes you to your current parent directory

 CD /D F:\Homework – changes Drive and directory at the same time

 MD \A\B\C\D – creates a directory tree

 SUBST B: F:\Data – creates virtual drive B: which is physically F:\Data

 SUBST H: F:\Homework - creates virtual drive H: which is physically F:\Homework

 SUBST B: /D – Deletes virtual drive B:

 SUBST H: /D - Deletes virtual drive H:

 ATTRIB +R /D – makes Directories Read-only too

 ATTRIB +A *.* /S – turns on the archive bits for all files in all subdirectories

 XCOPY *.* D: /SEMI (or /SHREK)

 *.* D: -copy all files to the D: drive

 /SEMI – /S copies all files in all subdirectories, - /E including all empty directories, - /M copies only files with the archive bit set on and then turns it off - /I assume the destination is a directory (not a file)

 /SHREK - /S copy all files in all Subdirectories - /H copy Hidden files - /R overwrite Read-only files - /E copy Empty files too - /K Keep all existing attributes
