Obsidian’s Behavior :
When Obsidian encounters a link like [[CLUSTERS/tto-cluster/qqq/tt|tt]], Obsidian simplifies the link to [[tt|tt]] because the full path is unnecessary for resolving the file.
Problem :
The simplified link loses the context of the full path, making it ambiguous if multiple files with the same name exist in different folders.
How to ensure that a normalized link like [[tt|tt]] always refers to the specific file [[CLUSTERS/tto-cluster/qqq/tt|tt]]
One way to ensure the full path is preserved is by using the full link format whenever possible, like [[CLUSTERS/tto-cluster/qqq/tt|tt]]. You could also try adding unique identifiers or tags to help distinguish files with the same name in different folders. It might be a bit more manual, but it avoids ambiguity.
