I've got a Perforce server set up, and installed the P4V client. I've created a new depot and a new workspace. Per the documentation, I've mapped the workspace to the depot. So far so good.
I now have a .SQL script that was created by an external application that I wish to check in for the first time. I copied the file into my workspace and can see the file in the client's workspace tree window. Yet when I attempt to mark the file for add, I get a "file(s) not opened on this client" error. I've tried editing a changelist to include the file, but the changelist editor does not "see" the file.
I've read through the documentation (PDF files), but I just do not see what I'm missing. I've worked with other RCS software in a commercial setting, but this is my first stab at trying to set up and administer and RCS system up for personal use.
