how to empty recyclebin through command prompt?

问题:

Usually we delete the recycle bin contents by right-clicking it with the mouse and selecting "Empty Recycle Bin". But I have a requirement where I need to delete the recycle bin contents using the command prompt. Is this possible? If so, how can I achieve it?

回答1:

You can effectively "empty" the Recycle Bin from the command line by permanently deleting the Recycle Bin directory on the drive that contains the system files. (In most cases, this will be the C: drive, but you shouldn't hardcode that value because it won't always be true. Instead, use the %systemdrive% environment variable.)

The reason that this tactic works is because each drive has a hidden, protected folder with the name $Recycle.bin, which is where the Recycle Bin actually stores the deleted files and folders. When this directory is deleted, Windows automatically creates a new directory.

So, to remove the directory, use the rd command (r​emove d​irectory) with the /s parameter, which indicates that all of the files and directories within the specified directory should be removed as well:

rd /s %systemdrive%\$Recycle.bin

Do note that this action will permanently delete all files and folders currently in the Recycle Bin from all user accounts. Additionally, you will (obviously) have to run the command from an elevated command prompt in order to have sufficient privileges to perform this action.

I prefer recycle.exe from Frank P. Westlake. It provides a nice before and after status. (I've been using Frank's various utilities for well over ten years..)

C:\> recycle.exe /E /F
Recycle Bin: ALL
    Recycle Bin C:  44 items, 42,613,970 bytes.
    Recycle Bin D:   0 items, 0 bytes.
            Total:  44 items, 42,613,970 bytes.

Emptying Recycle Bin: ALL
    Recycle Bin C:   0 items, 0 bytes.
    Recycle Bin D:   0 items, 0 bytes.
            Total:   0 items, 0 bytes.

It also has many more uses and options (output listed is from /?).

Recycle all files and folders in C:\TEMP:
  RECYCLE C:\TEMP\*

List all DOC files which were recycled from any directory on the C: drive:
  RECYCLE /L C:\*.DOC

Restore all DOC files which were recycled from any directory on the C: drive:
  RECYCLE /U C:\*.DOC

Restore C:\temp\junk.txt to C:\docs\resume.txt:
  RECYCLE /U "C:\temp\junk.txt" "C:\docs\resume.txt"

Rename in place C:\etc\config.cfg to C:\archive\config.2007.cfg:
  RECYCLE /R "C:\etc\config.cfg" "C:\archive\config.2007.cfg"

nircmd lets you do that by typing

nircmd.exe emptybin

You can use a powershell script (this works for users with folder redirection as well to not have their recycle bins take up server storage space)

$Shell = New-Object -ComObject Shell.Application
$RecBin = $Shell.Namespace(0xA)
$RecBin.Items() | %{Remove-Item $_.Path -Recurse -Confirm:$false}

The above script is taken from here.

If you have windows 10 and powershell 5 there is the Clear-RecycleBin commandlet.

To use Clear-RecycleBin insider PowerShell without confirmation, you can use Clear-RecycleBin -Force. Official documentation can be found here

while

rd /s /q %systemdrive%\$RECYCLE.BIN

will delete the $RECYCLE.BIN folder from the system drive, which is usually c:, one should consider deleting it from any other available partitions since there's an hidden $RECYCLE.BIN folder in any partition in local and external drives (but not in removable drives, like USB flash drive, which don't have a $RECYCLE.BIN folder). For example, I installed a program in d:, in order to delete the files it moved to the Recycle Bin I should run:

rd /s /q d:\$RECYCLE.BIN

More information available at Super User at Empty recycling bin from command line

回答6:

To stealthily remove everything, try :

rd /s /q %systemdrive%\$Recycle.bin

回答7:

i use these commands in a batch file to empty recycle bin:

del /q /s %systemdrive%\$Recycle.bin\*
for /d %%x in (%systemdrive%\$Recycle.bin\*) do @rd /s /q "%%x"

I know I'm a little late to the party, but I thought I might contribute my subjectively more graceful solution.

I was looking for a script that would empty the Recycle Bin with an API call, rather than crudely deleting all files and folders from the filesystem. Having failed in my attempts to RecycleBinObject.InvokeVerb("Empty Recycle &Bin") (which apparently only works in XP or older), I stumbled upon discussions of using a function embedded in shell32.dll called SHEmptyRecycleBin() from a compiled language. I thought, hey, I can do that in PowerShell and wrap it in a batch script hybrid.

Save this with a .bat extension and run it to empty your Recycle Bin. Run it with a /y switch to skip the confirmation.

<# : batch portion (begins PowerShell multi-line comment block)
:: empty.bat -- http://stackoverflow.com/a/41195176/1683264

@echo off & setlocal

if /i "%~1"=="/y" goto empty

choice /n /m "Are you sure you want to empty the Recycle Bin? [y/n] "
if not errorlevel 2 goto empty
goto :EOF

:empty
powershell -noprofile "iex (${%~f0} | out-string)" && (
    echo Recycle Bin successfully emptied.
)
goto :EOF

: end batch / begin PowerShell chimera #>
Add-Type shell32 @'
    [DllImport("shell32.dll")]
    public static extern int SHEmptyRecycleBin(IntPtr hwnd, string pszRootPath,
        int dwFlags);
'@ -Namespace System

$SHERB_NOCONFIRMATION = 0x1
$SHERB_NOPROGRESSUI = 0x2
$SHERB_NOSOUND = 0x4

$dwFlags = $SHERB_NOCONFIRMATION
$res = [shell32]::SHEmptyRecycleBin([IntPtr]::Zero, $null, $dwFlags)

if ($res) { "Error 0x{0:x8}: {1}" -f $res,`
    (New-Object ComponentModel.Win32Exception($res)).Message }
exit $res

Here's a more complex version which first invokes SHQueryRecycleBin() to determine whether the bin is already empty prior to invoking SHEmptyRecycleBin(). For this one, I got rid of the choice confirmation and /y switch.

I use this powershell oneliner:

gci C:\`$recycle.bin -force | remove-item -recurse -force

Works for different drives than C:, too

回答10:

Yes, you can Make a Batch file with the following code:

cd \Desktop

echo $Shell = New-Object -ComObject Shell.Application >>FILENAME.ps1
echo $RecBin = $Shell.Namespace(0xA) >>FILENAME.ps1
echo $RecBin.Items() ^| %%{Remove-Item $_.Path -Recurse -Confirm:$false} >>FILENAME.ps1


REM The actual lines being writen are right, exept for the last one, the actual thigs being writen are "$RecBin.Items() | %{Remove-Item $_.Path -Recurse -Confirm:$false}"   
But since | and % screw things up, i had to make some changes.

Powershell.exe -executionpolicy remotesigned -File  C:\Desktop\FILENAME.ps1

This basically creates a powershell script that empties the trash in the \Desktop directory, then runs it.

回答11:

All of the answers are way too complicated. OP requested a way to do this from CMD.

Here you go (from cmd file):

powershell.exe /c "$(New-Object -ComObject Shell.Application).NameSpace(0xA).Items() | %%{Remove-Item $_.Path -Recurse -Confirm:$false"

And yes, it will update in explorer.
