Use ISRLOCKED() or ISFLOCKED() to find out whether someone else (not this same user in this same session) has already placed a lock. USE [file] EXCLUSIVE indeed locks the whole table.
You can also use RLOCK() and FLOCK() to find out the status. A simple RLOCK() / FLOCK() returns False if the table is locked by someone else.
