"exec factoryreset" doesn't delete script files --- where are they?

[JoelMSnyder]

Folks:

I am trying to do a large deployment of Fortigate devices, and as part of that there is a lot of factoryreset going on while we test out our deployment procedures.  This is v6.2.3 in case it matters.

One thing I have discovered is that script files that were uploaded and executed seem to still be "known" by the FortiGate, even after factoryreset.  I don't know if they are on disk somewhere or if this is just some funky history log that is floating around, but obviously I would like to clean that out so that we don't confuse people. 

How can I get the FortiGate to forget these script files ? 

Thanks...
