Commented Unassigned: Creation date [15]

Hi, Im just using the newest version of SPfilezilla but when i upload to SharePoint the creation date is modified to the date im uploading. I see in the specifications of this program that it should reserve the originally date.
Am i doing something wrong?"
Best regards,
perry
