[Owncloud] How can I rebuild the filesystem cache?

[Uwe Koloska]

Hello,

just tried to find a problem with an audio dir that is not correctly handled 
by owncloud.  After fixing something that might have been the problem -- more 
on this later ;-) -- I have not found a way to rescan all (or just a single 
directory) of files, so I got the wrong informations from the cache ...

Is there a way to rescan all files (or a single directory) of a user?  Like it 
is done after an update of some sort? Maybe I have to touch a single file to 
make owncloud believe it has to rescan?

Thank you for listening
Uwe
