Hey guys and girls,
I have some hardcore problem on opening some files from my System W on my Server (I do not have the right / privelege to open). These files have been moved from my System U to the Server. If I rename one of these files using my System U I can open it from my System W without any problem.
This is the first time I got this problem since the server is installed (ca. 6 months ) and I can not reproduce this situation.
From all other Linux Desktops I have no problem to open the files by any user account.
System W:
Windows 7 with all updates till today 
Logged in User: roxane
System U:
Ubuntu 18.04.5 LTS
Logged in User: Administrator
Server:
OMV 4.1.34-1
share: SMB/CIFS with ACLs
See below file AR TGN 1.pdf could not be open.
After renaming the file AR TGN 2.pdf to b.pdf as mentioned before it could be opened without any problem.
I can not see where the difference is 
!
It would me extremely great if somebody can help me.
Thx in advance
