If you're alluding to COPY.TXT meaning COPYRIGHT.TXT and therefore it would/should contain a license then I hate to disappoint you. Copyrights and Licenses are different things. So maybe put a dampener on your expressions of incredulity, it's not a great way to engage here.
Afaik there's s really common convention of a file named COPYING with instructions on when you can/cannot copy the code, i.e. the license.
> What did you think "COPY.TXT" meant, in all honesty?
so I'm most focused on this one : SYNC Synchronize two directry trees
While I was lost in the folder sync tools, Copy.txt really just stood out as a readme honestly.
Edit: Readme of the implementation. Like all the rest.
