Hello.
A quick question:
How do I check the existence of a file?

Either try to open it with open(), or read the directory with dir() to see if it
is
there. If it isn't there, open() will give an error. If it isn't there, dir()
won't list it.

Try this function
global function filelen(sequence st)
object hasildir
hasildir = dir(st)
if atom(hasildir) or length(hasildir) = 0 then
return -1
end if
return hasildir[1][3]
end function
st is name of the file.
return -1 if file not exist
return 0 if file 0 bytes or opened for writing
return else = file size
