When properly configured, DirSize can be tailored to run overnight and
collect statistics about all your file servers, and about who is using the most
on its own will display usage information.
||Default: Current path
The folder to process. This may be a
UNC path (\\computer_name\share_name\path). Folder names with special characters such as
spaces must be entered with double quotes e.g.
c:\> dirsize "Program Files"
||Display command line help
||Default: All levels (255)
Limits the number of levels of
folders displayed to the given value. Eg -1 will only show the first folder level. The
statistics will include all levels, but they will not be displayed. This is very useful if
you just need to find out how much total space is in use by an application without caring
how it is divided into sub-folders. A value of 0 is equivalent to a value of 255 (i.e. all
||Show the wasted space per folder as a
percentage of the folder's used space (default).
||Show the actual wasted space per folder rather than as a
percentage of the folder's used space.
||Control which characters to use for drawing lines.
DOS's graphical line drawing characters even if it detects that its output is being
- Uses portable text line drawing characters even if it detects that its output is not
being redirected. This is useful if the result is going to be used on another computer,
for example, on a Unix machine or a Macintosh.
Note: When DirSize detects that its output is being redirected, it automatically turns
off pagination, and selects portable characters to draw lines, such as +, - and |. It does
this because the output may be sent to a device or another computer that does not
understand DOS's line drawing characters (which are non-portable). When DirSize's output
goes to the screen, it uses the DOS line drawing characters. You can override the default
behaviour in either case using the -c option
||Show how much disk space would be wasted if the cluster size
was set to # bytes per cluster. # is restricted by DOS to powers of two, but for
convenience DirSize allows it to be set to any value. This is useful for previewing the
result of a change in cluster size on a set of files. In general, the smaller the cluster
size, the smaller the wasted space. As for -size=# above, a K, M or G suffix can be used.
||Print the result in a comma-delimited output format suitable
for importing into a spreadsheet, database or word processor.

||Displays web browser at Crystal Software's home
||In this mode, DirSize does not round up the space used by
each folder (the local size, not including any subfolders). DirSize also ignores the space
used in each folder by DOS for housekeeping.
||Displays web browser on DirSize's Home Page
||Show a report of the paths exceeding 255
characters, or those with invalid characters in their names.
||Send mail to the author
||Displays this manual
||Disable display of file count column.
||Ignore offline files in the statistics
||Disable the drive statistics shown at the end of the report.
||Do not show sub folder counts in square brackets
||Do not show folder totals on the left hand side
||Disables display of the header in the CSV and
||Do not show wasted space for each folder. The wasted space is
still included in the totals - it is just not shown as a display column.
||Displays DirSize order form
||Do not paginate the output. Pagination pauses after each
screenful of output. [Enter] shows the next line, [Esc] exits, [End] scrolls continuously
to the end of the output, and any other key shows the next screen full of output.
Pagination is automatically disabled when the output is redirected.
||Displays web browser to purchase DirSize
||Only show folders that use # space or larger. A K, M or G
suffix can be used to express the value in KBytes (1024 bytes), MBytes (1024 KBytes) or
GBytes (1024 Mbytes). This is very useful for finding network space hogs, or for
eliminating small folders that are of no consequence from the display.
Specifies the sort order:
- Name - sort by folder name in alphabetical order.
- Local - sort by local size, largest first.
- Total - sort by total size, largest first.
- Waste - sort by wasted space, largest first (not as percentage of overall space).
- Files - sort by number of files, largest first.
- None - do not sort.
This may be useful if you are comparing DirSize's output to an unsorted listing from
the DOS DIR command - each folder is displayed in the same order it was retrieved from
||Same as -comma above but outputs in tab-delimited format.
||Displays help/welcome screen
Subfolders whose name exceeds the Windows maximum path length will not be
processed. Any statistics regarding them will be ignored. You can handle these
by mapping a drive letter to the point deep in the folder path.
For some reason the path was not found. It will be excluded from the
