everything first goes into the opaks folder.
then it gets "processed" into the right places. So when initially downloaded, everything ends up in opaks.
But that should dissappear within seconds as it gets processed, unless a problem happened.
@sam_uk, Your link is not up.
Its possible that storage is full, for example. See if emptying out helps. Older files that remain in opaks may never get processed, but watch if newer files are still not being processed.
