Synapse doesn't learn when files and directories are on the mix.

I've seen how Synapse 'learn'. For example, using several calls that start with 'v' and match VLC, will map 'v' to VLC:

    Ctrl+Space v ---> VirtualBox
    Ctrl+Space vl ---> VLC
    Ctrl+Space v ---> VirtualBox
    Ctrl+Space vl ---> VLC
    Ctrl+Space v ---> VLC ...Bingo!

However this behavior does not work the same when there are a match for both a file path and its root directory. Until recently I was able to open the directory '~/Downloads' like this:

    Ctrl+Space Downl ---> Download directoy

However I had the unfortunate choice to open a file on Downloads:

    Ctrl+Space file ---> Download/file.txt

Now Synapse got stuck on the file.

    Ctrl+Space Down ---> 'Download/file.txt'

I've tried to make it relearn by doing:

    Ctrl+Space Down ---> 'Download/file.txt' + (Down Arrow to Download directory) + Enter ---> Downloads/

But doesn't stick, even if I repite it several times. I've even tried many times:

    Ctrl+Space Down ---> 'Download/file.txt' + (Rigth Arrow to Places) + Enter ---> Downloads/

In short by opening a file inside a directory, I've lost the ability to gain access to the directory easily. It is SO bad that even this won't work:

    Ctrl+Space Downloads /----> 'Downloads/file.txt'

I would gladly provide more information and do some testing if requested.
Regards.
