Remote file access confusion

Hi
I have a SMB share on a QNAP box which contains a folder tree. In these various folders are calc documents which need to access other files within the same set of folders.

I’m looking for a way to reference these other files from within the spreadsheet - no matter which machine / platform the user is running on. The trouble is: when I open the spreadsheet from some machine the file references in the doc are all based on the user’s local environment, not the NAS box.

This must be a very common scenario but I’m stumped . . :frowning:
Any helpers ??

Check that Tools → Options → Load/Save → General, both “Save URLs relative to file system” and “Save URLs relative to internet” are enabled.
