Use case or problem
When using the multi-select in the File Explorer, the right-click (context) menu currently is only aware of the file directly under the click. Instead, the actions should apply to the entire selection.
This would allow for bulk move, copy, and delete from the File Explorer.
Proposed solution
If multiple items are selected in the File Explorer, the context menu should be aware of all the files in the selection. This will require updating the file-menu event to expect an array of TFiles. Then all the listeners will need to handle one or multiple TFiles. Some actions (such as rename) should only be added if files.length === 1.
Current workaround (optional)
Since these are all filesystem actions, they can be done from the OS file explorer.
