# MacOS paths
|

# ===========
|
|
# MacOS directory separator is a colon ":" which is the only character not
|
|
# allowed in filenames.
|
|
#
|
|
# A path containing no colon or which begins with a colon is a partial
|
|
# path.
|
|
# E.g. ":kalle:petter" ":kalle" "kalle"
|
|
#
|
|
# All other paths are full (absolute) paths. E.g. "HD:kalle:" "HD:"
|
|
# When generating paths, one is safe if one ensures that all partial paths
|
|
# begin with a colon, and all full paths end with a colon.
|
|
# In full paths the first name (e g HD above) is the name of a mounted
|
|
# volume.
|
|
# These names are not unique, because, for instance, two diskettes with the
|
|
# same names could be inserted. This means that paths on MacOS are not
|
|
# waterproof. In case of equal names the first volume found will do.
|
|
# Two colons "::" are the relative path to the parent. Three is to the
|
|
# grandparent etc.
