Угу. Ну, ещё раза два-три спрошу, опосля, может быть, запомню .

dassen, что делать, если есть, например, и каталог F-LDR003, и каталог F-LDR003__MY?

There.cmd

Код:

@echo off
setlocal enableextensions enabledelayedexpansion

for /f "usebackq delims=" %%i in (
	`2^>nul dir /b /a:d ^| findstr.exe /i /r /c:"^F-LDR.*" ^| findstr.exe /i /v /r /c:".*__MY$"`
) do (
	if not exist "%%~i__MY\." (
		echo Rename folder [%%~i] into [%%~i__MY].
		ren "%%~i" "%%~i__MY"
	) else (
		echo Can't rename folder [%%~i] into [%%~i__MY] because folder [%%~i__MY] already exists.
	)
)

endlocal
exit /b 0

…and…

Back Again.cmd

Код:

@echo off
setlocal enableextensions enabledelayedexpansion

for /f "usebackq delims=" %%i in (
	`2^>nul dir /b /a:d ^| findstr.exe /i /r /c:"^F-LDR.*__MY$"`
) do (
	set sFolderName=%%~i
	set sNewFolderName=!sFolderName:~0,-4!

	if not exist "!sNewFolderName!\." (
		echo Rename folder [%%~i] into [!sNewFolderName!].
		ren "%%~i" "!sNewFolderName!"
	) else (
		echo Can't rename folder [%%~i] into [!sNewFolderName!] because folder [!sNewFolderName!] already exists.
	)
)

endlocal
exit /b 0
