* In peony-qt, file copy operation has 2 types.

* 2. Other.
* If case 1, the peony-qt will trying to copy a file with special suffix automaticly.
* For example, a file abc.xyz will be copied and renamed to abc(1).xyz, abc(2).xyz...
* If case 2, there will be nothing special action in operation except it went into error.
* \deprecated
* use FileDuplicateOperation instead.
