I have this nuxeo fast-track 5.7.3 installation :
nuxeo-dm-5.7.3, nuxeo-social-collaboration-5.7.3, nuxeo-drive-1.1.2.
All documents put in the nuxeo-drive folder are uploaded on the server except txt files.
This document never appears in the folder on the server (in nuxeo-dm or nuxeo-sc interface)
On the other hand, when I create the same txt document in the interface, it's ok. The txt file appears in the nuxeo drive folder.
Thank you.
Patrick
