Thanks, Dan. I understand this, and i also have seen this manner of working in other experienced users who send a folder with tons of .pd files (and it often takes a while to figure out which one to open).
Guess whoever sends a messy thing is the one to blame. There's no feature that will prevent people from being clumsy and writing dirty patches and stuff.
I agree with Dan that Pd currently offers ways to be clean and organized when it comes to this matter.
