More than 20 people have been reported in connection with historical child abuse after police reviewed thousands of old records.
Det Ch Insp Catriona Henderson said the creation of a national police force offered new opportunities to make connections.
She said: "We're policing in different circumstances. We are now Police Scotland and we've got the benefit of the resource that that brings with it.
"Prior to the creating of Police Scotland it was eight legacy forces, so we can now identify opportunities and make links - and also make use of technology advances to progress investigations that perhaps were not possible to progress in the past.
"We would, for example, be able to identify a person who had been subject of an investigation in one part of Scotland and then find there's been another one in another part of Scotland - and marry those two up, and use that as a form of corroborative evidence in some cases."
So far about 8,500 files have been collected which fit the terms of reference of the Scottish Child Abuse Inquiry - cases where the victim was abused while in care.
The operation is expected to carry on until the end of the Child Abuse Inquiry which is scheduled to last until at least next autumn.
