Let Users Decide
Filed under: 
he OS X Finder overwrites directories without aggregating files in both source and the destination. For example, when a directory called /Photos is copied to /Directory/Photos, it will delete its the contents of /Directory/Photos rather than merging. That serves as a case study where the user is not sufficiently involved and, consequently, data can be lost. This behaviour must have been inherited from Mac OS 9 as Linux does not have this problem and neither does Windows.
Yesterday I spent hours driving myself mad as I realised I had lost data 4 months ago. No back-ups could resurrect that data. File dialogues must always be verbose as data loss is the most frustrating experience of all.

Developers must begin to involve users in choices that are made, as the example above suggests. “Easier-to-implement” or “automatic” are usually a bad idea. For the very same reasons, for example, image2.jpg appears after image10.jpg in file managers. That is simply a common ‘bug’ that mushroomed into a norm.
