For now Theia don't have Reveal in File Explorer, Theia's Reveal in Explorer only locate file in resouce manager.
I think this real functional, can we consider adding this feature?

I believe the command already exists for electron (#10523), not sure what it would look like in the browser:

theia/packages/navigator/src/electron-browser/electron-navigator-menu-contribution.ts

Lines 28 to 34 in 7c90401

	export const OPEN_CONTAINING_FOLDER = Command.toDefaultLocalizedCommand({
	id: 'revealFileInOS',
	category: CommonCommands.FILE_CATEGORY,
	label: isWindows ? 'Reveal in File Explorer' :
	isOSX ? 'Reveal in Finder' :
	/* linux */ 'Open Containing Folder'
	});

@ouliuquan Do you run Theia in Electron or browser mode? I agree with Vince here, I believe it might not be possible to implement this feature in browser mode. VSCode also only has it when running locally in Electron.

@vince-fugnitto Yes, I use the offical Eclipse Theia Blueprint, and my own build yarn electron package, this function(show file in file explorer) didn't show in Tabs, but show in Project Manager field.

My OS: Windows 11
