Свободное место на диске команда windows

Неплохой скрипт. Только будет требовать повышенных прав запуска в ОС >= Vista с UAC.

Особенно понравился момент сравнения меня с яндексом ))

Дам Вам еще пищу для размышлений.
Только что написал от себя (хоть и деревянный), но рабочий скрипт поразрядного деления (с разг. «деление в столбик»). Т.е. еще другими словами: обход ограничения CMD на предельное значение числового типа данных.
Можете воспользоваться наработкой:

И для Вас еще пару идей, которые думаю будет интересно реализовать:

1) такой скрипт не требует повышения прав:

1
2
3
4
5
6
7
8

@echo off
for /f "skip=1 tokens=1-3" %%i in ('2^>nul ^
WMIC LogicalDisk ^
WHERE "DriveType='3'" ^
GET Name^, Size^, FreeSpace') do (
  echo %%i-%%j-%%k
)
pause

Где что, разберетесь. Здесь требуется красивый перевод в гигабайты.
Лучше конечно постепенно делить на 1024 и смотреть сколько цифр остается (соответственно такой префикс и подставлять).

2) такой скрипт тоже требует повышенных прав, но он показывает в единицах, уже сконвертированных к приемлемым величинам:

Алгоритм:
1. Берете предыдущую WMIC, прогоняете каждый том под циклом, подставляя в такой текст
select volume c:
detail volume
select volume d:
detail volume
и т.д. постепенно формируете внешний текстовой файл.
2. Выполняете команду

1
2
3

diskpart /s имя текстового файла сценария
::Или 
type scenario.txt | diskpart | findstr "Емкость Свободное"

3. Результат парсите по две строки.
Уфф. Вообщем, по-разному можно.

You can avoid the commas by using /-C on the DIR command.

FOR /F "usebackq tokens=3" %%s IN (`DIR C: /-C /-O /W`) DO (
    SET FREE_SPACE=%%s
)
ECHO FREE_SPACE is %FREE_SPACE%

If you want to compare the available space to the space needed, you could do something like the following. I specified the number with thousands separator, then removed them. It is difficult to grasp the number without commas. The SET /A is nice, but it stops working with large numbers.

SET EXITCODE=0
SET NEEDED=100,000,000
SET NEEDED=%NEEDED:,=%

IF %FREE_SPACE% LSS %NEEDED% (
    ECHO Not enough.
    SET EXITCODE=1
)
EXIT /B %EXITCODE%

UPDATE:

Much has changed since 2014. Here is a better answer. It uses PowerShell which is available on all currently supported Microsoft Windows systems.

The code below would be much clearer and easier to understand if the script were written in PowerShell without using cmd.exe as a wrapper. If you are using PowerShell Core, change powershell to pwsh.

SET "NEEDED=100,000,000"
SET "NEEDED=%NEEDED:,=%"

powershell -NoLogo -NoProfile -Command ^
    $Free = (Get-PSDrive -Name 'C').Free; ^
    if ($Free -lt [int64]%NEEDED%) { exit $true } else { exit $false }
IF ERRORLEVEL 1 (
    ECHO "Not enough disk space available."
) else (
    ECHO "Available disk space is adequate."
)

Get-Volume для просмотра свойств логических разделов дисков

Просмотреть объём свободного и занятого места каждого логического диска вы можете командлетом

Get-Volume

Значение полей следующее:

• DriveLetter — буква диска (или тома)
• FriendlyName — метка диска
• FileSystemType — тип файловой системы
• DriveType — тип диска (Fixed это постоянный диск, а Removable это съёмный диск, например, внешний USB диск или флешка)
• HealthStatus — статус здоровья
• OperationalStatus — статус работы
• SizeRemaining — оставшийся размер (свободное место на диске)
• Size — общий размер диска

Как узнать количество свободного места на определённом диске

Вы можете получить информацию о конкретном диске, для этого укажите его букву с опцией -DriveLetter:

Get-Volume -DriveLetter C

Как вывести только размер свободного места на диске

Если вам нужен только данные о свободном месте на диске, то используйте следующую конструкцию:

(Get-Volume -DriveLetter C).SizeRemaining

Предыдущая команда выведет размер свободной области к байтах, чтобы перевести в гигабайты и терабайты используйте следующие конструкции (не забудьте указать букву интересующего вас диска вместо «C»):

(Get-Volume -DriveLetter C).SizeRemaining/1GB
(Get-Volume -DriveLetter C).SizeRemaining/1TB

Как просмотреть размер неразмеченных дисков

Диски с неразмеченными областями, например, новые диски или диски с неподдерживаемой файловой системой (например диски Linux) не отображаются предыдущими командами.

Смотрите также: Почему Windows не видит новый диск

Для просмотра размера всех дисков, в том числе без буквы, используйте команду:

Get-Disk

Вы увидите общий размер дисков, даже если они ещё не размечены.

Get-PSDrive – универсальный командлет для просмотра свойств всех типов дисков

Командлет Get-PSDrive получает диски в текущем сеансе. Вы можете получить конкретный диск или все диски в сеансе.

Этот командлет получает следующие типы дисков:

• Логические диски Windows на компьютере, включая диски, подключённые к общим сетевым ресурсам.
• Диски, предоставляемые поставщиками PowerShell (например, диски Certificate:, Function:, и Alias:), а также диски HKLM: и HKCU:, предоставляемые поставщиком реестра Windows PowerShell.
• Временные диски, указанные в сеансе, и постоянные подключённые сетевые диски, которые вы создаёте с помощью командлета New-PSDrive.

Начиная с Windows PowerShell 3.0, параметр Persist командлета New-PSDrive может создавать подключённые сетевые диски, которые сохраняются на локальном компьютере и доступны в других сеансах.

Кроме того, начиная с Windows PowerShell 3.0, когда к компьютеру подключается внешний диск, Windows PowerShell автоматически добавляет PSDrive в файловую систему, представляющую новый диск. Вам не нужно перезапускать Windows PowerShell. Точно так же, когда внешний диск отключается от компьютера, Windows PowerShell автоматически удаляет PSDrive, представляющий удалённый диск.

Итак, запустим Get-PSDrive без опций:

Get-PSDrive

Вывод довольно обширный, возможно не вся информация вам требуется.

Для сокращения выводимых данных можно указать интересующий диск:

Get-PSDrive C

Теперь проще разобраться и найти интересующие поля, связанные с количеством занятого и свободного пространства на диске:

• Used — использовано места на диске
• Free — свободно места на диске

Чтобы вывести информацию только о дисках файловой системы, используйте команду:

Get-PSDrive -PSProvider FileSystem

Чтобы вывести только информацию об используемом и свободном пространстве определённого диска выполните команду:

Get-PSDrive C | Select-Object Used,Free

Чтобы сделать вывод более читаемым (выведет только количество свободного пространства на диске):

Get-PSDrive C | Select-Object @{Expression={$_.Free/1GB}}

Следующая команда выведет количество свободного и используемого пространства на диске:

Get-PSDrive C | Select-Object @{Expression={$_.Free/1GB}},@{Expression={$_.Used/1GB}}

Для получения информации об используемом и свободном пространстве диска удалённого компьютера используйте следующую команду (необходим Powershell Remoting):

Invoke-Command -ComputerName SRV2 {Get-PSDrive C} | Select-Object PSComputerName,Used,Free

You can’t just add stuff to a drive forever, be it your main hard drive, the little flash drive in your pocket, or the giant external hard drive on your desk.

Even an arguably humongous 16 TB hard disk has a limit: 16 TB! As crazy as it sounds, it, too, can fill up. True, it’ll take two million high-quality photos to do it, but «only» about 150 feature-length 4K movies.

Performance Suffers on a Full Hard Drive

Regardless, you get the idea—you may need to check the free space on a drive from time to time, especially if it starts to slow down or act funny, which is very often the not-so-clear consequence of too much stuff in a single place.

Unfortunately, especially in Windows operating systems, you don’t get a friendly «Hey, your hard drive is almost full!» warning. Instead, you get strange behavior, cryptic error messages, or serious problems like a Blue Screen of Death (BSOD).

How to Check Free Hard Drive Space in Windows

Fortunately, it’s super easy to check how much free space you have on any of your drives, and it only takes a minute or two.

1. In Windows 11 or Windows 10, select the Start button, followed by File Explorer (the small folder icon). If you don’t see it, check under the All apps or Windows System folder, or type file explorer into the search box.

   In Windows 8 or Windows 10, search for this pc and then select This PC.

   In Windows 7 or Windows Vista, select the Start button, followed by Computer.

   In Windows XP, go to Start and then My Computer.

2. On the left-hand side of File Explorer or Windows Explorer (depending on your version of Windows), make sure This PC, Computer, or My Computer is selected (again, based on your version of Windows).

   If you don’t see anything on the left side of this screen, open the View menu and enable the Navigation pane. In older versions of Windows, go instead to Organize > Layout > Navigation Pane (7 and Vista), or View > Explorer Bar > Folders (XP).

3. On the right-hand side, find the drive on which you want to know how much free space is left.

   In Windows 11/10/8, all storage devices are listed in the Devices and drives area. In Windows 7/Vista/XP, Hard Disk Drives and Devices with Removable Storage are listed separately.

4. In newer versions of Windows, you can see right under the drive listing how much free space is left on it, as well as the total size of the drive, in a format like this:

   Local Disk (C:)
   [storage space indicator]
   535 GB free of 931 GB
   

   If that’s all you need to know then you’re done! However, there is a bit more information about your drive’s capacity buried just a bit deeper:

5. To see more, right-click or tap-and-hold the drive you want more storage space information on, and then choose Properties.

6. In the General tab, you’ll see all the important details about the storage device you’re looking at, reported in bytes as well as rounded GB.

   • Used space is the sum total of every piece of data on this device.
   • Free space is the difference in the total formatted capacity of the device and the sum total of every piece of data being stored on it. This number indicates how much more storage you’re allowed to fill.
   • Capacity is the total formatted capacity of the drive.
   • Also there is a pie graph, showing used vs free space on the drive, helpful for visualizing how much space you’re using on this hard drive or other device.

You should now know exactly how much hard drive space is available on your computer. If you’re running low, delete files you don’t need or move them to a different hard drive that has more free space.

How to Check Free Hard Drive Space Using Command Prompt

Another way to check free space is with Command Prompt. The results aren’t as easy to read because the values are represented in bytes instead of gigabytes, but it’s still possible with this command:

wmic logicaldisk get size,freespace,caption

How Much Free Space Do You Need?

Microsoft has historically recommended that to avoid problems, you should leave at least 100 MB of free space on whatever drive you have Windows installed on. However, because we’ve seen issues at levels higher than 100 MB, we have always recommended 10 percent free space instead.

How to Disable Low Disk Space Checks in Windows

Calculate 10 Percent Free Space on Windows PC

To calculate 10 percent free space, just take the number next to Capacity from Step 6 and move the decimal to the left one space. For example, if the hard drive you’re viewing has a total capacity of 250.0 GB, moving the decimal one space to the left makes it 25.0 GB, meaning that you shouldn’t let the free space drop below that for that particular device.

Examine Types of Files Taking Up Storage Space

In Windows 11 & 10, much more detail about what sorts of files are using up your drive’s capacity can be found in Settings > System > Storage. Just choose a drive you’re interested in and Windows will analyze it, breaking it down into categories like System & reserved, Temporary files, Apps & features, Pictures, and more.

There are also several free disk space analyzer tools that’ll show you which files and folders are occupying the most space.

In any version of Windows, choosing Disk Cleanup from the drive’s properties (Step 6 above) will start the Disk Cleanup utility, a one-stop-shop for removing files that are no longer needed by Windows.
