# Grouping

The **Grouping** tab in the *Folder Format* dialog lets you choose which column (if any) the file list is [grouped](/directory-opus/manual/basic_concepts/sorting_and_grouping.md) by.

* **Group by**: Select the column to group the list by, from the dropdown list. This column doesn't have to be displayed.
* **Scheme**: If multiple [grouping schemes](/directory-opus/manual/preferences/preferences_categories/file_display_columns/evaluator_groups.md) have been defined for the group, you can pick the scheme from this dropdown.
* **Sort groups**: Choose whether groups should be sorted in ascending or descending order.
* **Combine**: Choose how to handle similar values:
  * **Combine similar values**: A range of similar values will be put in a single group (e.g. A-H).
  * **Never combine values**: Instead of A-H you would have A, B, C, D, E, F, G, H, etc. This is only really useful for text fields like *User description*.
  * **Singletons in 'Other' group**: Similar values won't be combined, except for groups with only one member (which will be combined into a group called 'Other').
* **Collapse all groups initially**: File groups will start out as collapsed instead of expanded.
* **Put folders in their own group**: No matter how files are grouped, all folders will be placed into their own group.
