Need some major batch-fu.

Question

I have this massive folder structure with thousands of folders and subfolders. I need to copy all the DLLs from this structure into a single folder.

I've tried the

xcopy *.dll c:\output /S /E

but that copies the DLLs with the structure.

Is there a way to do what I want in a batch file using DOS commands only.

Answer 1

Assuming no spaces in folder/file names:

for /r %f in (*.dll) do copy %f %~nf.dll
