    Greetings:

    Within my task scheduler, Windows Defrag is configured as such:

    %windir%\system32\defrag.exe -c-i-g

    I believe -c is to defrag my c:\ drive.

    What are the switches -i and -g for?

    Thanks in advance...j

  2. defrag volume [/a] Analyzes the volume and displays a summary of the
    analysis report.

    defrag volume [/a] [/v]

    defrag volume [/v] Displays the complete analysis and defragmentation
    reports.

    When used in combination with /a, displays only the analysis report. When
    used alone, displays both the analysis and defragmentation reports.

    defrag volume [/f] Forces defragmentation of the volume regardless of
    whether it needs to be defragmented.

    /? : Displays help at the command prompt.

    Thanks for the info. However, what does -c and -g do. Maybe it is an error
    in Vista setup?

    Hi, JCG.

    As Ǝиçεl said:
    At the Command Prompt, simply type:
    defrag /?

    That should produce what I call a mini-Help file that shows the switches and
    parameters available with the defrag command - and the syntax for using
    them. This shows that all the switches use the slash "/" character, rather
    than hyphen "-". Many commands will actually accept a variety of such
    characters; I don't know if defrag will accept "-" for "/". And they
    usually are not fussy about "c" or "C" - but they are insistent on the colon
    when referring to volume ("drive") letters.

    Use defrag /c to "Perform the operation on all volumes". Specify defrag C:
    to operate only on Drive C:.

    This does not show -i or -g as available switches, and I don't know what
    those do. They may be a part of Task Scheduler, rather than of Defrag.
