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

* 1. The file is duplicated in same folder.
|
|
* 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.
