Checksum file for every folder/file automatically?

I'm using Windows HashCheck Shell Extension and it works by right clicking a file/folder and creating a checksum file for the entire file. The issue with this is this is manually done and that if I try to make a checksum for a large number of files at once, it lumps it all together into ONE checksum file whereas I would like multiple smaller checksum files for every folder (so checking also doesn't take forever and that I dont have to create new checksum files since more files within the checksum means changes more likely to happen and a new file is needed to be made).
