Trouble with multify "Unable to open X for reading&quot

Im a real newb at Panda3d, I was just trying to use multify to create and extract a multifile, but everytime I try to extract or even view the files inside I get:
Unable to open x.mf for reading
:cry:
Ive tried tons of times.

I know this is probably not something wrong with multify, but with my computer, but I can’t seem to get what’s happening

make sure the multifile is in the right location. Usually, you will want it in the same directory as your main script. Also, you will need to mount the multifile to the virtual filesystem in your script. put this into your main script:

from pandac.VirtualFileSystem import VirtualFileSystem
from pandac.Filename import Filename
...
#mount virtual filesystem
vfs = VirtualFileSystem.getGlobalPtr()
vfs.mount(Filename('x.mf'), '.', VirtualFileSystem.MFReadOnly)

after that, you should be able to load your file from within the multifile.
