Default Lister and expand folders

Sometimes, I lose the tree folders extension from the dual display of the default Lister.
I make some test and, look and try to understand code in file /dopusdata/layout/system/default.oll.

My default Lister layout is:

  • Single display
  • This PC to default path
  • Root items expended (Quick access, This PC, Desktop and Collections)

With Dual lister closed but with:

  • This PC to default path
  • Root items expended (Quick access, This PC, Desktop and Collections)

With this default Lister saved, I can see in default.oll:

Now, I open Lister and change default path to C:\.
In default.oll file, I can see that <tree2> is removed.

Also, I see in default.oll <curdir>.

What are these paths used for ?

Are those branches pinned, or just expanded?

Is Preferences / Folder Tree / Expand/Collapse / Collapse non-selected branches on?

See my reply in TabGroupName.otg - curdir? - #2 by Leo

Just expanded with this option off.

Seems to be solved now, thanks.

Another thing about dual display and folders expansion.
Expanded folders are saved in default lister for tree 1 and 2.
If Opus is restarted after changing language or update, open dual file display don't respect expension of tree 2.
