# "Maximum Path Length Limitation
|
|
# In the Windows API, the maximum length for a path is MAX_PATH, which is
|
|
# defined as 260 characters. A local path is structured in the following
|
|
# order: drive letter, colon, backslash, name components separated by
|
|
# backslashes, and a terminating null character. For example, the maximum
|
|
# path on drive D is "D:\some 256-character path string<NUL>" where
|
|
# "<NUL>" represents the invisible terminating null character for the
|
|
# current system codepage. (The characters < > are used here for visual
|
|
# clarity and cannot be part of a valid path string.)"

# This will test the limit of a filename in MySQL at 512 bytes.
|
|
# We control that by making it a relative path starting with "./".
