Saving and Loading Trees

Go to Tree > Save Tree in the toolbar, or use the keyboard shortcut:

• macOS: Cmd+S
• Windows/Linux: Ctrl+S

A file dialog appears. Choose a location and filename. The file is saved with the .tree extension.

A .tree file contains:

• Tree structure - All nodes in the game tree, including any nodes you have manually added or deleted in the tree editor.
• Game parameters - Player count, stack sizes, blind sizes, ante, dead money.
• Bet sizing configuration - Open-raise sizes, 3-bet sizes, postflop SPR tables, all-in thresholds, and all other tree-building settings.
• Starting ranges - If you have set custom starting ranges for a postflop tree, these are included.

A .tree file does not contain:

• Solved strategies (those are saved as .iks sim files).
• Solver settings (threads, iterations, abstraction) - these are separate from the tree.

Go to Tree > Open Tree in the toolbar, or use:

• macOS: Cmd+O
• Windows/Linux: Ctrl+O

Select a .tree file. The tree loads and you can view it in the tree editor, modify it, or run a solve on it.

• Before solving - Save your tree configuration before running a long solve. If the application closes unexpectedly, you can reload the tree without reconfiguring everything.
• Reusable configurations - Save trees that represent common scenarios you study (e.g., "6max 100bb cash", "HU SB vs BB 50bb"). You can load them later, adjust parameters, and solve again.
• Sharing - Tree files can be shared with other IkaSolver users. They can load your tree and run their own solve with their preferred settings.
• After editing - If you have manually edited the tree (adding or removing nodes), save to preserve your edits.

If you want to save your solved results, use Sim > Save Sim instead.
