SW and Owncloud

Hi all

I am seconded to a customer who uses SW18 SP5 with Owncloud for storage.
The cloud is "connected" like a windows drive (so appears as a normal directory)
I have problems with files that "corrupt", a priori, when SW closes.
The phenomenon of corruption is not systematic.
Interestingly, if a colleague sends me a copy of the file from their instance and I put it back into my cloud instance, the file works again.

For a while we thought about a synchronization problem like shutting down the machine too quickly but somehow it wasn't coherent since the files are necessarily synchronized since it's my machine that creates them.

I have gone through this discussion: https://forum.mycad.visiativ.com/t/solidworks-et-dropbox-ou-equivalent/106477, without finding anything relevant.

Have you encountered this kind of behavior with this cloud or another?

On Monday, I will take screenshots of the messages, it may illustrate better.
