I have a problem when a user creates a new file... this is the scenary: A user creates a new file in the network path: public_html\owncloud\data\user\file\folderexample\newfileexample.txt
If I access from web service I can see the new file, and if I close the client aplication (3.2.3) and reopen, the client syncronize without problems... but if he doesnt close it the client aplication, can be delayed about 48 hours ¡!... some idea?
Yes. You can run it periodically, it depends on the performance of your system how often you want to run it. NFS does not have a way to do notfications. SMB via Windows Network Drive does. We have implemented this for customers, you can test it out via marketplace.owncloud.com.
