How are Relative vs Absolute paths marked?

Development

Thanks for the direction.

It looks like GEDCOM7 file paths works in a similar manner. Except that they store a default base directory path in the Header and explicitly use the RELA tag again to state that the object’s path (which, unlike Absolute paths, does not start with a slash directory separator) is relative to the same base directory.

This SuperTool script (a "SuperTool Script" type Note in .gramps XML format) can be pasted into the [**Import Text** add-on gramplet](https://gramps-project.org/wiki/index.php/Addon:ImportGramplet). Pressing the Import button creates the Note.

Then switch categories to Media and use the SuperTool addon tool to import the the script from the Note (File → Load from Note). Select some Media object and use the Execute button to show which which use Absolute or Relative paths.
