In the local email management pane, you can manage local emails and folders in the same way as in the Windows Explorer window. In specific, you can:
Click the folder to rename, click again or right-click and select Rename from the popup menu; Enter the new name, once the name edit box is shown.
Right-click on the emails/folder to copy, and select Copy from the popup menu; Navigate to the destination folder; right-click the local pane area, other than emails names, select Paste from the popup menu.
Select the emails / folder to delete, click on button or press Delete key; Select Yes on the confirmation message box if you want to delete, or click on No if you don't.
Right click the target sub folder and select Rename option from the popup menu; Enter the new name, once the name edit box is shown.
Right click the sub folder, and select Cut / Copy from the popup menu; Navigate to the target folder; Right click the local emails, select Paste from the popup menu.
Select the sub folder to delete, click on button or select Delete option from the right-click menu; Select Yes on the confirmation message box if you want to delete, or click on No if you don't.
Select the target sub folder, then drag / drop this folder to the destination local folder. This is the same with cut-paste a sub folder.
