Reproduced with oC 10.1.1 10.2. and 10.2.1

@owncloud/qa Can someone please check if it is an issue in order to triage (cc @micbar jfyi)

I think this problem is specific for ownCloud WebDAV External storages. Because ownCloud is trying to upload file with .part extension. If external storage is also an ownCloud server, the remote server does not accept upload because .part extension is blacklisted for ownCloud.

I installed two ownCloud server and added one of them as External Storage for the other. When an upload attempted to external storage, external storage server logs are indicating to this line as error reason: https://github.com/owncloud/core/blob/master/lib/private/Files/View.php#L1875

Moving to backlog - not considered for 10.2.1
