[Archetypes-users] Does ExternalStorage ever delete the files it stores?

[Ken W. <ke...@su...>]

Trying to use ExternalStorage, I'm finding that the "Delete current file"
radio-button option seems to do nothing.  

That is, I select "Delete current file" and save the edit form, and: 

* the previously uploaded file still shows up unchanged

* in the "view" tab the file still available for download, and 

* out on the file system the file is still there.

Tracing thru the ExternalStorage code, all that the "Delete" option seems to
do is (eventually) call ExternalStorage.unset(), which in turn calls
self.setTempData(), which "Sets temp data into ES storage".  Nowhere along
this way can I find anything resembling a file delete. 

I've been customizing ES to some extent, so maybe I've inadvertently
disabled something.  However, when I go back and reinstall it and just try
the unmodified "ExternalExample", it still happens.

Surely I must be overlooking something blindingly obvious.  Can anyone tell
me what it is?
