Yeah, we should maybe do what already have done for file system providers. Add an option options: { recursive: boolean }

@bpasero I have updated the API and make sure the data travels to the bulk-edit-service but it seems that the textfile-service doesn't know about recursive folder delete

@jrieken that's right because the IFileService does not expose any option to not delete recursively. I am not sure there would be any other client, so why not assert this within the bulkEditService and bail out early if the folder is not empty, similar to how it already bails out if the file exists: https://github.com/Microsoft/vscode/blob/39b91f6c674882ef20fbde20b95ed6c01cd3a576/src/vs/workbench/services/bulkEdit/electron-browser/bulkEditService.ts#L345

I'd say that once we expose the full 'reading'-api for file system provider we will encounter this again (see #48034). Sure, we can do a short term trick in the bulk edit service but I think the fileservice/textfileservice-couple is the place that should have this. Likely also true for ignoreIfExists (which we might nuke again...)
