thanks for your suggestions...I'll give them a go.
I'll get back to you after I've tested it. As we're all volunteers it might take me some time to do so.
Again thanks for your help.
I can't be sure, but I suspect it will be *all* to do with permissions.
This may mean that you should consider very carefully how you use the NAS for storage, I'm wondering if it wise to rely on mixed file system searching in this scenario.
You might want to consider a different approach, than mounting shared folders on different OS based machines?
e.g
Cloud Station for Synology NAS
Or you may need a more robust client/server netwrok to actually give you the reliability and data management you need.
I'm sure some-one with more experience will chime in at some point!
