*
* The only significant difference from QDir is that the root path is not
* '/', but an empty string since that's how the file paths are stored in
* the archive. However, QuaZipDir understands the paths starting with
* '/'. It is important in a few places:
*
* - In the cd() function.
* - In the constructor.
* - In the exists() function.
* - In the relativePath() function.
*
* Note that since ZIP uses '/' on all platforms, the '\' separator is
* not supported.
