Transaction-like copy/move directories

When user move one file TC doing good job: check available space, ask delete if cancel. But when moving dirs and choose cancel TC ask to delete only last file. Ex: Move C:\Mp3\Singer1 to D:\Mp3 - when cancelled user can F8 on D:\Mp3\Singer1 - not NICE Ex2:

  Job 1: move C:\Mp3\Singer* to D:\Mp3 (background, space available) 
  Job 2: move C:\Mp3\Group* to D:\Mp3 (background, space available before end of job 1...)

So when user cancel job 2 its leving mess in D:\Mp3 and there is no space available on disk for job 1...

With transactional-like copy/move it will be nicer..

I don't thing about full ACID transactions :) Someone, if can, pleas correct my English, pleas...
