Complexity: 4
Refs: #29030

This milestone we have started to work on the multi root experience, currently this is only available on insiders. Verify:

• Quickly check that the single root explorer is the same as before
• You can nicely transition from single root to multi root (from File menu, from explorer context menu, via global action)
• View state is preserved in the explorer between restarts (focus, expand state, opened editor)
• The active file is always revealed when switching between editors
• You can drag and drop in the explorer (also between different roots)
• All the context menu actions make sense (check the ones for the roots as well as clicking into the empty space outside any root)
• All the explorer actions (top right) make sense and target the currently selected element
• Deleting, renaming, adding file should work as before
• Check the case when you have the same folder opened twice - once the parent and once any of its children (try to rename / delete something in that folder, both parents should get updated)
• Have a files.exclude setting in each folder and make sure that it is exactly respected in each folder
• Delete the root folder in some other tool while vscode is open. Make sure vscode handles this case gracefully
• Be creative in trying to break the explorer

Failures:

• No context-menu on folders (sub & root).
• "Copy" (Cmd+C or via context-menu) not working -> Not pasting with Cmd+V & "Paste" invisible in context menu.

Working:

• Moving a file or folder with drag & drop.
• Context-menu on files.

Questions:

• How to choose "Copy" while drag & drop, e.g. while holding Ctrl key?
• Undo for drag & drop operations planned?

@Dominik-K this is work in progess, please do not test it out yet.

[isidorn]

Please test this with the latest insiders build found on https://vscode-builds.azurewebsites.net/builds/insider since the released insider build has an issue with explorer reacting to file events

Works quite well 👍

The only question for me is the use-case of opening overlapping folders. Perhaps in this case, the overlapping folder can be removed from the container:

e.g.

• open root folder vscode
• open root folder vscode\src
• perhaps in the Explorer, the folder src should not be shown anymore and it should only be shown as a top level root folder.

[isidorn]

Thanks. I am still questioning this scenario in general.

An alternative would to what you are suggesting is to show the vscode/src but grayed out and not be exapndable. That way it would be clearer to the user.

I can cover @stevencl on Linux now.
