fileGetSize bad argument, expected scriptfile, got string

[BlueTheFurry]

Hello, i want to get the size of the file "test.dff", but the problem is, when i try to get it, it just throws me this error back:

"[expected scriptfile at argument 1, got string "test.dff" ]

my code:

  
local theFile = "test.dff" 
fzb = fileGetSize(theFile) 
local fz = fzb/1024

fileGetSize takes in a file userdata variable, not a string. You need to use fileOpen first.

local theFile = fileOpen("test.dff") 
fzb = fileGetSize(theFile) 
local fz = fzb/1024

Thanks, that did the trick
