A READER ASKS
We are building a FileMaker based Asset Management System and will be using the reference method for the actual assets. I’m trying to find a way to limit the file type being uploaded to an “alias” only. Is there a way to do this in a calculation in the container filed?

Well, by default you can setup the Insert File script step to have the Reference only option set. I think that the user could still remove the check.

Here you can see the reference only option for the Insert File script step.

Now you can use a calculation to look at the size of the inserted file by using the length function. Here is a link where I discuss that topic.

DYK: Length Function And Container Object Size

Here you can see size of a container file using a reference (alias) and the size of a container with the file embedded.
