I got wired issue today saying [NQSError:61013] File error, There has been a sharing violation
This problem came to me when I was developing repository object and I left it open for 2-3 days. And again when I started back after 3 days it was not allowing me to save changes which I done.
Just open the RPD in online mode and make some changes in repository and save it. If you don't want to loose the change stop the server, save and then close the administrator, and start the server
