One problem with the recent OS X versions: When one copies a file from one disk to another, the system considers it a modification, and displays the date of the copying as the "date modified". This is a PITA when one is dealing with several versions of a document and making backups.
Is there a way to have the system pay attention only to =real= modifications of the file content?
