8 | # The "8.3 rule" is loose: "if reducing the directory entry names |
9 | # within one directory to lowercase and 8.3-truncated causes | |
10 | # conflicts, that's a bad thing". So the rule is NOT the strict | |
11 | # "no filename shall be longer than eight and a suffix if present | |
12 | # not longer than three". | |
