Hey Niels,

thanks for the quick reply. We are in fact using mediadb and from what I se=
e the files do come from the filesystem. Doesn=E2=80=99t ZMS take care of t=
his itself when using getData() on a file field?

My problem is that the data return from the mediadb by ZMS does not work wi=
th video files - any other files work just fine. The files themselves do no=
t reside in the ZODB but in the filesystem.

I=E2=80=99d love to see your code snippet to read the actualy file from the=
 mediadb.=20

Best
Sebastian
