Description: In the F:\Download folder, there are subfolders 1, 2, 3, 4, 5. The problem is to keep subfolders 1 and 2 and delete the remaining three folders. Use the following program. But it only keeps folder 1 and deletes the others.

for /f "skip=1 tokens=*" %%i in ('dir F:\Download\ /b /ad ^|find /v "F:\Download\1,2"') DO rd /s /q "F:\Download\%%i"
del F:\Download\*.* /a/q/f

Everyone, please help see how to modify the above program to achieve the purpose of keeping subfolders 1 and 2!

Thank you in advance!

Just tried it. It doesn't work.

@echo off

for /f %%i in ('dir F:\下载\ /b /ad ^|findstr ""') DO rd /s /q F:\下载\%%i

pause

According to the LZ's idea, this p needs to be executed under F:\Download.

The result of dir F:\Download\ /b /ad is:

1
2
3
4
5

@echo off

for /f %%i in ('dir F:\Download\ /b /ad ^|findstr ""') DO rd /s /q F:\Download\%%i

pause

The method on floor 6 is good. Thanks.

This is too simple. Consider something more complex.

The test path structure is as follows:
test
- test1
- test2
- test21
- test22
- test221
- test3
- test31
- test311
- test32

Requirements:

Delete all folders except test22 and test311.
The original directory structure is retained.
The test221 directory should be deleted.
The files under test31 should be deleted.

Hehe, thank you everyone, learned it...

I tried it using the method of moderator lxmxn, and such an error appeared on my computer: "findstr is not an internal or external command, nor is it a runnable program or batch file". What's the reason? Please help from the experts. Is it because of my DOS version?

Please state your operating environment.

Having spaces is definitely not okay

Please save the content as "Delete Folders and Files Other Than Folders.bat" and run it in the directory

@echo off
::Delete all files other than itself
for %%a in (*) do (if "%%a" neq "Delete Folders and Files Other Than Folders.bat" del "%%a" /q)
::Delete all folders other than the specified folders
for /d %%b in (*) do (if "%%b" neq "1" if "%%b" neq "2" rd "%%b" /q/s)
