Hi, JCG.
As ????????l 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.
