Comparing all codes in different folders?

Question

I know how to compare two files' codes. Just open the two codes in notepad++ and Plugins->Compare

But how can I compare all codes in different folders when there are simply too many files?

For example, let's say in my PC there are two folders C:/A and C:/B

And these two folders have the same files a.py and b.py

I want to compare a.py in C:/A and a.py in C:/B, and compare b.py in C:/A and b.py in C:/B.

Solution

You can use something like Beyond Compare to compare file sets. There are plenty of other tools out there that will do this too.

No idea why this would be off topic, totally important and relevant

WinMerge is perfect here. It is opensource and completely free to use. winmerge.org/?lang=en
