No. QFileSystem gives you access to *the* filesystem on your system. There 
aren't two.

If you want custom, please consider modifying your operating system's kernel, 
or using a virtual filesystem layer. Trying to make QFile be a VFS was a 
mistake back in Qt 4.1 days we're only now correcting.

You can still do the same by using your own classes deriving from QIODevice 
instead of relying on QFile. KDE has been doing that with the KArchive classes 
for 10 years.
