如何使用命令提示符删除空文件夹？

for /f "usebackq" %%d in (`"dir /ad/b/s | sort /R"`) do rd "%%d"

from: http://blogs.msdn.com/b/oldnewthing/archive/2008/04/17/8399914.aspx

Of course I'd test it first without deleting before I do that command. Also, here's a modded version from the comments that includes folders with spaces:

 for /f "usebackq delims=" %%d in (`"dir /ad/b/s | sort /R"`) do rd "%%d"

P.S. there are more comments in the blog post that might help you out so be sure to read those too before you try this out

A simpler way is to do xcopy to make a copy of the entire directory structure using /s switch. help for /s says Copies directories and subdirectories except empty ones.

xcopy dirA dirB /S

where dirA is source with Empty folders. DirB will be the copy without empty folders

You don't need usebackq:

FOR /F delims^= %%A IN ('DIR/AD/B/S^|SORT/R') DO RD "%%A"

Adding to corroded answer from the same referenced page is a PowerShell version http://blogs.msdn.com/b/oldnewthing/archive/2008/04/17/8399914.aspx#8408736

Get-ChildItem -Recurse . | where { $_.PSISContainer -and @( $_ | Get-ChildItem ).Count -eq 0 } | Remove-Item

or, more tersely,

gci -R . | where { $_.PSISContainer -and @( $_ | gci ).Count -eq 0 } | ri

well, just a quick and dirty suggestion for simple 1-level directory structure without spaces, [edit] and for directories containing only ONE type of files that I found useful (at some point from http://www.pcreview.co.uk/forums/can-check-if-folder-empty-bat-file-t1468868.html):

for /f %a in ('dir /ad/b') do if not exist %a\*.xml echo %a Empty

/ad : shows only directory entries
/b : use bare format (just names)

[edit] using plain asterisk to check for ANY file (%a\* above) won't work, thanks for correction

therefore, deleting would be:

for /f %a in ('dir /ad/b') do if not exist %a\*.xml rmdir %a

You can use the ROBOCOPY command. It is very simple and can also be used to delete empty folders inside large hierarchy.

ROBOCOPY folder1 folder1 /S /MOVE

Here both source and destination are folder1, as you only need to delete empty folders, instead of moving other(required) files to different folder. /S option is to skip copying(moving - in the above case) empty folders. It is also faster as the files are moved inside the same drive.

This is a hybird of the above. It removes ALL files older than X days and removes any empty folders for the given path. To use simply set the days, folderpath and drive

@echo off
SETLOCAL
set days=30
set folderpath=E:\TEST\
set drive=E:


::Delete files
forfiles -p %folderpath% -s -d -%days% -c "cmd /c del /q @path "


::Delete folders
cd %folderpath%
%drive%
for /f "usebackq delims=" %%d in (`"dir /ad/b/s | sort /R"`) do rd "%%d"`

from the command line: for /R /D %1 in (*) do rd "%1"

in a batch file for /R /D %%1 in (*) do rd "%%1"

I don't know if it's documented as such, but it works in W2K, XP, and Win 7. And I don't know if it will always work, but it won't ever delete files by accident.

Install any UNIX interpreter for windows (Cygwin or Git Bash) and run the cmd:

find /path/to/directory -empty -type d

To find them

find /path/to/directory -empty -type d -delete

To delete them

(not really using the windows cmd prompt but it's easy and took few seconds to run)

@echo off
set /p "ipa= ENTER FOLDER NAME TO DELETE> "
set ipad="%ipa%"
IF not EXIST %ipad% GOTO notfound
IF EXIST %ipad% GOTO found
:found
echo DONOT CLOSE THIS WINDOW
md ccooppyy
xcopy %ipad%\*.* ccooppyy /s > NUL
rd %ipad% /s /q
ren ccooppyy %ipad%
cls
echo SUCCESS, PRESS ANY KEY TO EXIT
pause > NUL
exit
:notfound
echo I COULDN'T FIND THE FOLDER %ipad%
pause
exit

It will be worked fine. This is best way to delete old files and remove empty directories recursively. following .bat file is,

forfiles /p [PATH] /s /m [FILE-PATTERN] /d -[DAYS] /c "cmd /c del @path"
for /f "delims=" %%d in ('dir [PATH] /s /b /ad ^| sort /r') do rd "%%d"

The placeholders needs to be replaced as follows (without the quotation marks):

[DAYS] = Max. age of the files in days, e.g. “10”
[PATH] = Path to search for old files and empty folders, e.g. “C:\Backup\”
[FILE-PATTERN] = Pattern that matches files to delete, e.g. “*.bkp”

The script has been successfully tested under Windows 7 and Windows Server 2003.

If you want to use Varun's ROBOCOPY command line in the Explorer context menu (i.e. right-click) here is a Windows registry import. I tried adding this as a comment to his answer, but the inline markup wasn't feasible.

I've tested this on my own Windows 10 PC, but use at your own risk. It will open a new command prompt, run the command, and pause so you can see the output.

1. Copy into a new text file:

   Windows Registry Editor Version 5.00

   [HKEY_CURRENT_USER\Software\Classes\directory\Background\shell\Delete Empty Folders\command] @="C:\Windows\System32\Cmd.exe /C \"C:\Windows\System32\Robocopy.exe \"%V\" \"%V\" /s /move\" && PAUSE"

   [HKEY_CURRENT_USER\Software\Classes\directory\shell\Delete Empty Folders\command] @="C:\Windows\System32\Cmd.exe /C \"C:\Windows\System32\Robocopy.exe \"%V\" \"%V\" /s /move\" && PAUSE"

2. Rename the .txt extension to .reg

3. Double click to import.

This can be easily done by using rd command with two parameters:

rd <folder> /Q /S

• /Q - Quiet mode, do not ask if ok to remove a directory tree with /S

• /S - Removes all directories and files in the specified directory in addition to the directory itself. Used to remove a directory tree.

for /r "D:\Music" /d %F in (.) do @dir /b "%F" | findstr "^" >nul || rmdir %~fF

D:\Fun is the folder that contains empty folders double quotation in the case of space in folder name (no need in this example)

A more modern and easier solution is:

forfiles /p C:\Path\To\Folder /c "cmd /c if @isdir==TRUE rd @file"

This will attempt to execute rd on all the directories located in C:\Path\To\Folder. Directories that have content in them will not be deleted.

If you exclude /p C:\Path\To\Folder then it'll run in the current directory.

If you add /s (before the /c) then it'll also look in sub-directories.

The following .cmd is an experiment (that works) to:

• Deletes empty directories and included "Old"(-1days) files under %temp% & C:\Windows\Temp folders,
• makes an cmd output log to a .txt file, about fouded & deleted folders/files .

%temp% = C:\Users(user)\AppData\Local\Temp | %userprofile%\AppData\Local\Temp

code:

::  This is a .cmd file
::    Use to:
::        Writes a Log about Temporary files & folders.
::        Cleans 'Windows Temp' folders/files.    (%userprofile%\AppData\Local\Temp  -&-  %windir%\Temp)
::        - a 'Cleaning_LOGs.txt'  will be created or updated in  Documents Library.    (%userprofile%\Documents\Cleaning_LOGs.txt)
::
@echo off
title Log&CleanTemp


: Set the Path of 'Log file'  (%LogPath% variable)
set "LogPath=%userprofile%\Documents\Cleaning_LOGs.txt"
::  Note: ">> path\file.txt 2>&1" redirects cmd output to <path\to>\<log_file.txt>,    (will be created if does not exist)
::        (if exist, adds the new log at the end of the file, without deleting previous logs)


: Set  'C:\Windows\Temp'  (%WinTemp% var.)
set "WinTemp=%windir%\Temp"


: Seperator [Header] with Date-Time between (any) previous Logs in <log_file.txt>
echo: >> %LogPath% 2>&1
echo ======================================== >> %LogPath% 2>&1
echo %date% - %time% >> %LogPath% 2>&1

Note that: The trigger to Experiment with this, as part of a 'pre-process', was to prevent the specific (obsolete) driver of the (also obsolete) sound card from automatically reinstalling at each boot. And clean (ghosted) hidden Devices and more other. (...) (this note was just about to get an idea for the use)

So, in a few words: This is the part that cleans up the 'temp' garbage left behind and gives a report.
