isSep
Returns if the given byte is a valid path separator
join
Naively combines a series of paths with the native path separator.
joinZ
Naively combines a series of paths with the native path separator and null terminator.
resolve
On Windows, this calls `resolveWindows` and on POSIX it calls `resolvePosix`.
resolveWindows
This function is like a series of `cd` statements executed one after another.
resolvePosix

dirname
Strip the last component from a file path.
relative
Returns the relative path from `from` to `to`.
extension
Searches for a file extension separated by a `.` and returns the string after that `.`.
stem
Returns the last component of this path without its extension (if any):
ComponentIterator
A path component iterator that can move forwards and backwards.
fmtAsUtf8Lossy
Format a path encoded as bytes for display as UTF-8.
fmtWtf16LeAsUtf8Lossy
