批处理文件以递归方式从多个子目录复制和重命名文件

Question

I have a lot of files in subdirectories, which i want to have

• in one folder without subdirectories
• renamed with the uppermost directory as prefix followed by its genuine file name.

Eg:

dir1\dir2\dir3\fileA.abc --> Output\dir1-fileA.abc

dir4\dir5\fileB.def --> Output\dir4-fileB.def

I tried to adapt the solution given in Batch file to copy and rename files from multiple directories for my purposes with the following code, but it is getting stuck in an endless loop as it seems.

Any ideas how to fix this?

pushd "C:\SomeDirectory"
if not exist "Output\*" md Output
for /D %%D in (*) do (
    if /I not "%%D" == "Output" (
        for /R %%J in ("*.*") do (
            copy /B /Y "%%~fJ" "Output\%%D-%%~nxJ" >nul
        )
    )
)

It looks as though your Output directory is actually "inside" your source directory. Then when you are copying/moving files to Output - you are actually just increasing the number of input files that need to be processed. Classic endless loop:-)
