3395	RenMov to same fs performs a slow directory scanning	egmont		"Press F6 on a giant directory tree, and rename/move to another name/location within the same physical file system.

Actual behavior: A ""Directory scanning"" dialog pops up and scans its contents, which might take many seconds if the tree is large. You could press Skip in which case this step is skipped and the directory is moved, although it's not obvious from the name that it's not the moving that will be skipped.

Expected behavior: Just execute that one single rename() call and it's done. No dialog should be popped up and no expensive task should be performed for an O(1) operation.
