extend volume windows 10

I need to get total space and used space of a SAN volume in Windows. There are too many volumes on the server to mount using the Windows letter mount points. Instead the server software mounts all available volumes in C:\Volumes path.

wmic logicaldisk get volumename, size, freespace

is fast and works great, but it only lists the volumes mounted as Windows letters.

dir \s \a C:\Volumes\SomeVolumeName

returns the information I need, but it's very slow as it recurses through all the files. I have hundreds of thousands of files on each volume.

du C:\Volumes\SomeVolumeName

is slow for the same reason as the dir command.

Is there any other way to get fast stats on a volume from the Windows command line or even better from Python?

I think you are looking for psutil

psutil (python system and process utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports Linux, Windows, OSX, Sun Solaris, FreeBSD, OpenBSD and NetBSD, both 32-bit and 64-bit architectures, with Python versions from 2.6 to 3.5 (users of Python 2.4 and 2.5 may use 2.1.3 version). PyPy is also known to work.

And for you, particulary this part of the documentation :

You can get the requried data from the below script. Enter all the volumes in your system in the array $DriveLetter and it doesn't take much time to execute

foreach ($item in $DriveLetters)
$data=Get-PSDrive $item | Select-Object Used,Free
"Used Space in Drive $item : $UsedData"
"Free space in Drive $item : $FreeSPace"

Hope it HElps.

How to view free space of a mounted volume in windows 10 , However, the disk is obviously mounted and the files on it accessible. -. Is there a way to check how much space is free ? This thread is locked. You can follow the � I want the size of the volume, not the size of the filesystem. (For example, if you extend a spanned volume, in order to actually use that extra space the NTFS filesystem has to be resized too) Windows volume management tools such as Disk Management MMC snap-in tend to issue volume and filesystem commands together, but on e.g. Linux one can see that these are actually separate operations and

in this .bat script you can catch the volume free space in GB and compare it, you can to catch the total volume. try this:

for /f "tokens=2,3,4" %%a in ('echo list volume ^| diskpart') do (
::echo o volume %%b
::fsutil volume diskfree %%b:
set result=E
set size=0
set free=0
FOR /f "tokens=1,2*delims=:" %%i IN ('fsutil volume diskfree %%b:') DO (
::echo Dtotal "%%i"
    if "%%i" == "Total free bytes        " ( 
        FOR /f "tokens=1,2delims=(" %%m in ('echo %%j') do (
            ::echo splittotal %%i : %%n
            FOR /f "tokens=1delims=," %%k in ('echo %%n') do (
                ::echo splittotalGB %%i :%%k
                set free=%%k
        set result=A
    if "%%i" == "Total bytes             " (
        FOR /f "tokens=1,2delims=(" %%m in ('echo %%j') do (
            ::echo splittotal %%i : %%n
            FOR /f "tokens=1delims=," %%k in ('echo %%n') do (

                set size=%%k

Extend a basic volume, Disk Management showing free space that a volume can extend into. "C" # Script to get the partition sizes and then resize the volume $size� To check the total disk space left on your Windows 10 device, select File Explorer from the taskbar, and then select This PC on the left. The available space on your drive will appear under Devices and drives.

Viewing Your Drive Information with PowerShell -- Microsoft , Using Windows Management Instrumentation makes it easy to pull the FreeSpace, which is measured in bytes, as well as the capacity (size) of the drive; to further get more information about how the volume is configured. The Get-Volume cmdlet will return a Volume object or a set of Volume objects that match the specified criteria. Note: Dynamic volumes are supported only by the following cmdlets: Repair-Volume (chkdsk), Optimize-Volume (defrag), and Format-Volume (format) on basic disks and storage spaces.

How to find how much hard drive space is available, The Properties window displays the used space, free space, and the total capacity of the hard drive or other drives. Volume properties. Microsoft� Finding disk capacity and free space of a local computer is easy but not so easy from a remote computer, especially through a GUI interface. It’s much easier to utilize the power of PowerShell and here is how you can do it. Get-PSDrive is a native PowerShell cmdlet that lists all storage drives on your local system.

Windows Command line get disk space in GB, Under the not a batch file - forced requirements clause, next cmd one-liner could help: for /f "tokens=1-3" %a in ('WMIC LOGICALDISK GET FreeSpace^,Name^� When you try to use Disk Management to shrink a volume, usually C: drive, in Windows 10/8/7, you may find the shrinkable space is far less than the free space on that drive. You can also see a note as below: “You cannot shrink a volume beyond the point where any unmovable files are located.

  • This should give you all volumes: wmic volume get Capacity, FreeSpace, Label, Name.
  • wmic works only with volumes that have a letter assigned. That doesn't work in my case. I have more volumes than the letters in the alphabet.
  • It's using volume, not logicaldisk. It worked for me on a disk mounted in a folder without a drive letter. I wouldn't have suggested it otherwise. The Name field should be the folder where the volume is mounted.
  • Sorry, I missed the "volume" argument in your comment. It's odd. It lists some of the volumes but not all.
  • As noted in the docs, if you're using Python 3, then you can use shutil.disk_usage. This works with volume mountpoints on Windows.
  • psutil.disk_partitions only lists volumes that have a DOS drive letter. That's disappointing.
  • @eryksun you tried with psutil.disk_partitions(all=True) ?
  • I think this will work perfectly in my script: psutil.disk_usage(someVolumePath). It's very fast too. Thanks.
  • Yes, in the source you can see that it only iterates over "logical" drives (i.e. volumes mounted with a DOS drive letter) and that all=True means to include all drive types.
  • The volumes are mounted in subdirectories of C:\Volumes. They are not assigned DOS drive letters.
  • PowerShell has Get-Volume, e.g. foreach ($v in Get-Volume -FilePath C:\Volumes) {Write-Output ("Name: {0}`nSize: {1}`nFree: {2}`n" -f ($v.FileSystemLabel, $v.Size, $v.SizeRemaining))}.
  • My PS does not have Get-Volume. There is Get-WMIObject though, but it doesn't see all my volumes, kind of like wmic discussed above.
