We are in the process of transferring our files into a document management system. We currently have them stored in folders on a network share. I need to make all of the existing folders/files read only so that the users can open the files, make changes to them and then save them into the document managament software. I do not want them being able to save back to the network share. However, i do want for them to be able to go in and delete the file/folder from the network share once the file is successfully transferred into the document management software. What is the best way to accomplish this?
