> When a directory or file is deleted using rm or rmr, the subtree is moved directly to .Trash/Current. If there are two deleted objects with the same name but with different original paths it is not feasible to undelete them without storing additional information regarding the original paths. Instead if the full path of the deleting object is used while moving (replicating the complete path in .Trash/Current) it will be easier to undelete objects to its original paths.
