From the **Case Manager** tab, double-click on the desired **Case** to open it, and then navigate to **Import** sub-tab. 2. Using a Windows File Explorer, drag and drop the desired source files/folders onto one of the two available panes on the left: 1. Use the **Top** pane to create a **Single Custodian** for all sources. 2. Use the **Bottom** pane to create **Multiple Custodians**, one for each top-level source. 3. You can also use the ![CaseDashboardImportAddCustodian](https://kb.cloudnine.com/hs-fs/hubfs/Knowledgebase%20-%20Explore/CaseDashboardImportAddCustodian.png?width=189&name=CaseDashboardImportAddCustodian.png) button at the top-left to create **Blank Custodians** instead. ![CaseDashboardImportCustodianPanes](https://kb.cloudnine.com/hs-fs/hubfs/Knowledgebase%20-%20Explore/CaseDashboardImportCustodianPanes.png?width=600&name=CaseDashboardImportCustodianPanes.png) 4. Once at least one **Custodian** has been created, you can add sources directly into any custodian in the following ways: 1. From any File Explorer, drag and drop the desired source files/folders onto the ![CaseDashboardImportCustodianDragTarget](https://kb.cloudnine.com/hs-fs/hubfs/Knowledgebase%20-%20Explore/CaseDashboardImportCustodianDragTarget.png?width=160&name=CaseDashboardImportCustodianDragTarget.png) target area. 2.
