Notes

Autodesk documents that trusted paths are searched instead of the ordinary support-file search path.
Autodesk documents that URL strings may also be returned when appropriate.
In clautolisp, findtrustedfile searches the trusted folders only (TRUSTEDPATHS plus the implicit folders), so it returns a file only from a trusted location. See Normative Rules: Secure File Loading and Trust Model (this chapter).
