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."
)

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.

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."
)

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.

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

1) такой скрипт не требует повышения прав:

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.

Вот как найти емкость вашего диска, использованное пространство или свободное место

Вы не можете просто добавлять вещи на диск навсегда, будь то основной жесткий диск, маленькая флешка в вашем кармане или гигантский внешний жесткий диск на вашем столе.

Даже жесткий диск емкостью 16 ТБ имеет ограничение: 16 ТБ! Как бы безумно это ни звучало, оно тоже может наполниться. Правда, потребуется два миллиона фотографий высокого качества, но «всего» около 150 полнометражных 4K-фильмов.

Независимо от того, вы поняли – вам может понадобиться время от времени проверять свободное место на диске, особенно если он начинает замедляться или вести себя забавно, что очень часто является непонятным следствием слишком большого количества материала в единственное место.

К сожалению, особенно в операционных системах Windows, вы не получите дружеское предупреждение «Эй, ваш жесткий диск почти заполнен!» . Вместо этого вы получаете странное поведение, загадочные сообщения об ошибках или серьезные проблемы, такие как BSOD.

К счастью, очень легко проверить, сколько свободного места у вас есть на любом из ваших дисков, и это займет всего минуту или две.

Эти шаги работают для Windows 10, Windows 8, Windows 7, Windows Vista и Windows XP.

Как проверить свободное место на жестком диске в Windows

1. В Windows 10 нажмите кнопку «Пуск», а затем Проводник (значок небольшой папки). Если вы этого не видите, проверьте папку Система Windows или введите Проводник файлов в поле поиска.

   В Windows 8 или Windows 10 найдите этот компьютер и выберите Этот компьютер .

   В Windows 7 или Windows Vista нажмите кнопку «Пуск», а затем – Компьютер .

   В Windows XP перейдите в раздел Пуск , а затем Мой компьютер .

   Посмотреть, какая версия Windows у меня установлена? если вы не уверены, какой вы используете.

2. В левой части Проводника или Проводника Windows (в зависимости от вашей версии Windows) убедитесь, что Этот компьютер , Компьютер или Мой компьютер выбран (опять же, в зависимости от вашей версии Windows).

   

   Если вы ничего не видите в левой части этого экрана, откройте меню Вид и включите Панель навигации . В старых версиях Windows вместо этого выберите Организовать > Макет > Панель навигации (7 и Vista) или Просмотреть > Панель обозревателя > Папки (XP).
   

   
   

3. Справа найдите диск, на котором вы хотите узнать, сколько свободного места осталось.

   

   В Windows 10 и 8 все устройства хранения перечислены в области Устройства и диски . В Windows 7, Vista и XP Жесткие диски и Устройства со съемным хранилищем перечислены отдельно.

4. В новых версиях Windows прямо под диском вы можете увидеть, сколько на нем осталось свободного места, а также общий размер диска в следующем формате:

    Локальный диск (C :) [индикатор места для хранения] 49,0 ГБ без 118 ГБ 

   Если это все, что вам нужно знать, то все готово! Тем не менее, есть немного больше информации о емкости вашего диска, скрытой чуть глубже:

5. Чтобы узнать больше, щелкните правой кнопкой мыши или удерживайте нажатой клавишу на диске, на котором вы хотите получить больше информации о пространстве хранения, а затем выберите Свойства .

   

6. На вкладке Общие вы увидите все важные сведения об устройстве хранения, на которое вы смотрите, в байтах, а также в округленном ГБ … свободное место включает:

  wmic логический диск, получить размер, свободное пространство, заголовок
