Remove it using the same ‘find’ method you are using with the other remove commands.

/file remove [/file find name=YourFileName]

I was removed version 3.rc7 and instaled version 2.9.48.

I was very problems with add user with scripts.

I’ve had similar problems with 2.9.46 - Since I upgraded to 3.0rc5 (and 6 and 7) it seemed to be working OK.
