Perhaps, I badly used the "move" verb. My consideration was about the possibility to choose the place we want to define for a specific action. I mean in Word (and many other soft) one can decide to save a document anywhere in a HDD. But effectively we gone a have duplication of files containing different version of it.... So said than if one have saved the file elsewhere, we owe to pay attention to the place of the older version..... This can bring a lot of discrepancies...
You are right saying the "move" function does not really exist. To be complete, I understand the "move" function as a effective displacement of a folder or a group of folder. Understanding this, I do agree with you.
For the consideration of FCPX, I had to more deeply understand the complete DB philosophy installed in FCPX.
Today I do agree with what you say. But as a beginner, I was reacting as I was used to with many other soft.
Many thanks for your help and discussion! I appreciate a lot
