Specifies the folders from which AutoCAD has permission to load and execute files that contain code.

To minimize the possibility of loading and executing malicious code, always set the TRUSTEDPATHS system variable to unique,
read-only folders where your authorized applications are located. This includes the following file types:
- ARX, DBX, CRX, HDI files
- LSP, FAS, VLX, MNL, SCR files
- .NET assemblies
- VBA macros (DVB files)
- acad.rx
- JavaScript
- DLL files
NoteThe AutoCAD install folder, the Plugin folder (%ProgramData%\Autodesk\ApplicationPlugins), and all their subfolders are always
implicitly trusted.
Valid strings include the following:
- When TRUSTEDPATHS is set to one or more folder paths in quotes and separated by semicolons, the previously listed file types
are loaded from the specified folders.
- When TRUSTEDPATHS is set to "" (an empty string) or "." (a period), there are no trusted folder paths in addition to the implicitly
trusted ones.
- When TRUSTEDPATHS includes a folder that ends with \... (backslash and three dots), all of its subfolders are also trusted.
NoteWhen using AutoLISP, note that TRUSTEDPATHS does not add a path to the Support File Search Path. It simply provides permission use to an existing support path. Thus, an AutoLISP file must be located in a path listed in the Support File Search Path.
In some circumstances, it might be more convenient to specify the relative file path in the Filename parameter when using the LOAD function.
These paths can also be set on the Options dialog box 
Files tab or in the Deployment Wizard.
The setting of the SECURELOAD system variable determines whether other locations, including the current drawing folder, are
trusted. Signed DLLs are automatically trusted.
NoteBeginning with AutoCAD 2013 SP1, the reserved acad2013.lsp and acad2013doc.lsp files and their successors are loaded only from their default installation folders: <install folder>\Support and <install folder>\Support\<language> respectively.
