Free space in a CMD shell

Admin 1

Is there a way to get the amount of free diskspace of a disk or a folder in a CMD without having to install some thirdparty applications?

I have a CMD that copies a big file to a given directory and could of course use the errorlevel return from the copy command, but then I have to wait for the time it takes to copy the file (eg...to that then the disk is full and the copy operation fails).

I would like to know before I start the copy if it is any idea at all. Tried the DU.EXE utility from Sysinternals, but that show occupied space only.

If you run "dir c:\", the last line will give you the free disk space.

Edit: Better solution: "fsutil volume diskfree c:"

A possible solution:

dir|find "bytes free"

a more "advanced solution", for Windows Xp and beyond:

wmic /node:"%COMPUTERNAME%" LogicalDisk Where DriveType="3" Get DeviceID,FreeSpace|find /I "c:"

The Windows Management Instrumentation Command-line (WMIC) tool (Wmic.exe) can gather vast amounts of information about about a Windows Server 2003 as well as Windows XP or Vista. The tool accesses the underlying hardware by using Windows Management Instrumentation (WMI). Not for Windows 2000.

As noted by Alexander Stohr in the comments:

  • WMIC can see policy based restrictions as well. (even if 'dir' will still do the job),
  • 'dir' is locale dependent.

Using this command you can find all partitions, size & free space: wmic logicaldisk get size, freespace, caption

df.exe

Shows all your disks; total, used and free capacity. You can alter the output by various command-line options.

You can get it from http://www.paulsadowski.com/WSH/cmdprogs.htm, http://unxutils.sourceforge.net/ or somewhere else. It's a standard unix-util like du.

df -h will show all your drive's used and available disk space. For example:

M:\>df -h
Filesystem      Size  Used Avail Use% Mounted on
C:/cygwin/bin   932G   78G  855G   9% /usr/bin
C:/cygwin/lib   932G   78G  855G   9% /usr/lib
C:/cygwin       932G   78G  855G   9% /
C:              932G   78G  855G   9% /cygdrive/c
E:              1.9T  1.3T  621G  67% /cygdrive/e
F:              1.9T  201G  1.7T  11% /cygdrive/f
H:              1.5T  524G  938G  36% /cygdrive/h
M:              1.5T  524G  938G  36% /cygdrive/m
P:               98G   67G   31G  69% /cygdrive/p
R:               98G   14G   84G  15% /cygdrive/r

Cygwin is available for free from: https://www.cygwin.com/ It adds many powerful tools to the command prompt. To get just the available space on drive M (as mapped in windows to a shared drive), one could enter in:

M:\>df -h | grep M: | awk '{print $4}'

I make a variation to generate this out from script:

volume C: - 49 GB total space / 29512314880 byte(s) free

I use diskpart to get this information.

@echo off
setlocal enableextensions enabledelayedexpansion
set chkfile=drivechk.tmp
if "%1" == "" goto :usage
set drive=%1
set drive=%drive:\=%
set drive=%drive::=%
dir %drive%:>nul 2>%chkfile%
for %%? in (%chkfile%) do (
  set chksize=%%~z?
)
if %chksize% neq 0 (
  more %chkfile%
  del %chkfile%
  goto :eof
)
del %chkfile%
echo list volume | diskpart | find /I " %drive% " >%chkfile%
for /f "tokens=6" %%a in ('type %chkfile%' ) do (
    set dsksz=%%a
)
for /f "tokens=7" %%a in ('type %chkfile%' ) do (
    set dskunit=%%a
)
del %chkfile%
for /f "tokens=3" %%a in ('dir %drive%:\') do (
  set bytesfree=%%a
)
set bytesfree=%bytesfree:,=%
echo volume %drive%: - %dsksz% %dskunit% total space / %bytesfree% byte(s) free
endlocal

goto :eof
:usage
  echo.
  echo   usage: freedisk ^<driveletter^> (eg.: freedisk c)

Is cscript a 3rd party app? I suggest trying Microsoft Scripting, where you can use a programming language (JScript, VBS) to check on things like List Available Disk Space.

The scripting infrastructure is present on all current Windows versions (including 2008).
