I want to rename files in a directory based on the name of containing directory, like 

c:\bin\data01\foo.txt

to

c:\bin\data01\data01.txt

following the post How to get folder path from file path with CMD .

Microsoft has a good Batch Reference that explains how you can do a for loop to tokenize a file path and pull out the directory name...

http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/batch.mspx?mfr=true

If you have a file that contains a list of files, tmp.txt...

c:\temp\folder\foo.txt

you can parse those filenames in batch with...

for /F "delims=\ tokens=1,2,3" %%i in (tmp.txt) do call echo %%i %%k %%j

and that produces...

%%i = c: 
%%j = temp
%%k = folder

after that you can use the variable that matches the directory name as the filename in your copy. However, this that only works if all the paths are the same depth.

If you only need the parent directory name you can use something like the folowing which works for a maximum nesting level of 10.

ECHO %~p0>path.txt    
FOR /F "tokens=1,2,3,4,5,6,7,8,9,10 delims=\" %%G in (path.txt) DO (
IF NOT [%%G]==[] SET myVar=%%G
IF NOT [%%H]==[] SET myVar=%%H
IF NOT [%%I]==[] SET myVar=%%I
IF NOT [%%J]==[] SET myVar=%%J
IF NOT [%%K]==[] SET myVar=%%K
IF NOT [%%L]==[] SET myVar=%%L
IF NOT [%%M]==[] SET myVar=%%M
IF NOT [%%N]==[] SET myVar=%%N
IF NOT [%%O]==[] SET myVar=%%O
IF NOT [%%P]==[] SET myVar=%%P
)
DEL path.txt /F /Q
ECHO %myVar%
