How do I delete a corrupt file from the server?

[SFDave]

I have a project that has somehow become corrupted. I have tried to force
checkin several times, without success. In fact, it just cloggs up the
server queue, and then I have to have my admin clear and restart the server
queue.

I cannot delete it from the "Open" window by right clicking, because it's a
"Read Only" project, because Server thinks it's still checked out to someone.

Even if I clear my cache, it does not change the status.

I have saved it to a different file name on a local drive, and I'd like to
try to save the project back to the server if possible, but I want to delete
the corrupted files from the server first.

Does anyone know how to do this?

Thanks in advance,

Dave
