You could do this:
[% file = INSERT "path/to/file" %]
[% file.length %]
Note that this will throw an error if the file does not exist. You can use
TT's TRY/CATCH to catch that error.
However, reading the entire file into memory just to find out its size is kind
of a heavy solution. Another option would be to pass a method to the template
that just checks the size of the file with -s.
