A list of file names in a folder:
DIR /B > X:\FolderA.txt
where X: is a full path and not required if same folder as folderA
So make a batch:
1. Make FolderA.txt
2. Make FolderB.txt
3. FOR /f %%A in ('DIR /A:D /B "FolderB.txt" ^| FIND /V /C ""') DO SET
cnt=%%A
4. Make a loop:
FOR /L %%f IN (1,1,%cnt%) DO (
SET /P _Fname=%\!_Fname! echo !_Fname!>> X:\FolderC.txt
MORE +1 FolderB.txt
)
FolderC will contain file names from FolderB that are also in FolderA
