[thelist] Determining file size in CF5

[Aaron Johnson]

Hi Seth,

If you're using CFMX, you can do it quite easily by dropping into
Java... in fact here's a function for it:

function FileSize(filePath) {
  Var result = 0;
  Var fileObject = CreateObject("JAVA", "java.io.File");
  fileObject.init(filePath);
  if (fileObject.isFile()) {
     result = fileObject.length();
  }
  Return result;
}

Also, check out cflib.org filesys lib which has a couple functions (not
including the one mentioned above, although I've submitted it) for
getting the size of a file:
