Searching for files within a number of folders in command line in Windows 10

I'm trying to find the proper syntax for finding all the files with a specific name that are in a multitude of folders. So - I have a directory with 100+ folders, in each folder there are files that are uniquely named but have a similar string in each name (AC_DATA). I want to find the names and directories of all those AC_DATA* files. I've tried many combinations, this one works if I have the name of the folder:

dir -r C:\DATA[foldername] /b | findstr /s /i AC_DATA*

but this does not work when I want to find all the files that are in those folders. I need to find these files while not being in the C:\DATA\ directory. I can do this in Windows 7 and unix but 10 is stumping me.
