Windows批处理以覆盖文件夹和子文件夹中的现有文件

Question

I am not good in this. I really need help.

I have searched a lot but no luck.

I want to create empty files and replace existing in a folder and its subfolders.

From my search, I could find how to make a batch to delete.

set folder="test"
cd /d %folder%
for /F "delims=" %%i in ('dir /b') do (rmdir "%%i" /s/q || del "%%i" /s/q)

However, I want to replace the files with empty one, I tried this:

set folder="test"
cd /d %folder%
for /F "delims=" %%i in ('dir /b') do (echo. 2>"%%i")

But it is not working. I need this to replace all my existing files so after delete it should not be recovered.

Answer 1

Better quote the whole set command and use always quotes:

set "folder=x:\test"
cd /d "%folder%" ||(pause&Goto :Eof)
for /F "delims=" %%i in ('dir /b/A-D') do Type Nul >"%%i"

To not by mistake clear the current folder I added the ||(pause&Goto :Eof) in case the cd didn't work. This is a conditional execution on fail of the previous command
