Can Brokerage firms retain access to files after an associate broker changes brokerage firms?

Brokerages maintain access to listing/transaction files within their transaction management solution since an agent always submits things to them there (i.e. SkySlope, Dotloop, Transaction Desk, paper, etc). Currently within SkySlope Forms, associate brokers will maintain access to their files for personal record keeping, even if they change brokerages.
