At least 16 characters plus file extension is no problem. The question is: Is it a limitation in WED only or is also the engine affected?
I can't fully remember, but I think there was a limit to 22 characters for action names or the like.
The mean part is: actually it's 21 characters (guess the \0 string end marker counts) and I know I had problems due to that that I was trying to go with an action name exactly 22 chars long
Can't remember whether the engine crashed or the function just was not started, though.
