## Fold level

There is a convention that we use the separator `:` in the key name to represent property relationships. For example, a key with name `users:4590:name` can be a key that stores the user name of the user whose id is 4590.

Medis supports this convention out-of-box by making the name parts as the folder of the tree view:

By default, we only show the first part as folders. However, you can configure this on the preference window:

In the screenshot above, we set the "Max fold level" to 3, and the key list will look like:
