If you're just using the GUI, you can't. But, if you run a Command Prompt
in Administrator mode (right-click on it and select "Run as administrator"),
you can type "defrag x" (where x is the drive you want to defragment). To
get the full syntax, type "defrag /?". I'll include it here, too:
Syntax: defrag <volume> -a [-v]
defrag <volume> [{-r | -w}] [-f] [-v]
defrag -c [{-r | -w}] [-f] [-v]
Parameters:
Value Description
<volume> Specifies the drive letter or mount point path of the volume
to
be defragmented or analyzed.
-c Defragments all volumes on this computer.
-a Performs fragmentation analysis only.
-r Performs partial defragmentation (default). Attempts to
consolidate only fragments smaller than 64 megabytes (MB).
-w Performs full defragmentation. Attempts to consolidate all
file
fragments, regardless of their size.
-f Forces defragmentation of the volume when free space is low.
-v Specifies verbose mode. The defragmentation and analysis
output
is more detailed.
-? Displays this help information.
Examples:
defrag d:
defrag d:\vol\mountpoint -w -f
defrag d: -a -v
defrag -c -v
