trailing slash / in path syntax
If you see this path by itself, no context or explanation:
...you know that /ab1 is a directory off the root /, and that ab2 is a subdirectory; but ab3 could be either a subdirectory or a file, correct?
...then the trailing slash means that ab3 must be a directory?
If my above understanding is correct: Is it considered good practice to avoid ambiguity and always add the trailing slash after the last directory in a path?
