There are two hard drives with a large number of movies, and folders are created with movie names inside the hard drives. There are many duplicate movies in the two hard drives. How to use batch processing to find out the duplicate ones, that is, find out the folders with the same names in the two hard drives and output them to a notepad. Thanks!

for /f "delims=" %%i in ('dir /ad /b /s') do (
if defined "%~nxi" (
echo %%"%~nxi"%% ==== %~i >>list.txt
) else (
set ""%~nxi"=%~i"
)
)

Bump

It's really too novice, can't understand. Can you explain how to use it?

For example, if your two hard drives are E and F drives under the current system, then you can do this:

for /f "delims=" %%i in ('dir /ad /b /s E:;F:') do (
if defined "%~nxi" (
echo %%"%~nxi"%% ==== %~i >>list.txt
) else (
set ""%~nxi"=%~i"
)
)

Finally, the list.txt generated in the directory where the batch file is located should be the duplicate directories, but I haven't tested it.

The game upstairs I don't understand, can you help solve it, thank you first.
if defined "%~nxi" (
echo %%"%~nxi"%% ==== %~i

if defined var Check if variable var exists
Because of the non-standard characteristics of the directory name, quotes are used to close this variable name, so there is
if defined "%~nxi"
Then, if this variable exists, it means there is a duplicate, so output this duplicate folder path to list.txt
If it does not exist, set this variable
set ""%~nxi"=%~i"
