Throwing exceptions vs validating
I am conflicted between validating and/or throwing an exception.
In the general case what would be the best practice? It is sort of hard for me to describe exactly what I envision, but in short - I can validate or check everything before doing an operation or I could just let the operation perform itself and handle any exceptions that arise.
For example (and I remind you - I am asking for best practices for the general case, not this specific example):
Let's say I am copying some files. I can first enumerate through all files that will be copied, verify all source and destination directories exist and that the full paths of any copied files will not be longer than 260 characters, etc. or I could have a try-catch block that will handle every possible exception the copy method could throw.
Currently I am not sure which would be better. I have such a validating method but would also prefer to handle exceptions as well, just in case (because I have the spare time and resources).
Again, I'm asking for the best practices in the general case.
