Where can i find my custom brushes ?

Hi,

I'm installing a new PC and would like to retrieve my custom brushes from my old PC (CorelDraw X6).

Some people advised to look into C:\Users\${user}\AppData\Roaming\Corel\CorelDRAW Graphics Suite X6. Some others advised to look for *.nib files.

I couldn't find them there. So where they are stored ?

PS: I'm looking for these:
