Organize Program and Support Files
You can change the default directory structure for the program and support
files to suit your needs.
Overview of File Organization
AutoCAD uses support files for purposes such as storing customization
definitions, loading AutoLISP and ObjectARX applications, and describing
text fonts.
The default directory structure for the AutoCAD program and support files is
designed to efficiently organize those files into logical groups. If this
organization does not suit your needs, you can change it. However, some
applications look for certain files in specific locations, and you should verify
that your modifications do not conflict with the requirements of those
applications. Without the full path, including drive and directory, AutoCAD
can locate only those files that are found in the library search path.
The location of the support folder changed in AutoCAD 2004. The location of
local customizable files is stored in the LOCALROOTPREFIX system variable.
The location of roamable customizable files is stored in the
ROAMABLEROOTPREFIX system variable. If a network supports roaming,
customizable files in the user's roaming profile are available on the machine
the user is logged onto.
The following LISP script creates the CUSTFILES command, which launches
Windows
®
Explorer in the correct folder.
(defun c:custfiles ()
(command "shell"
(strcat "explorer \"" (getvar "roamablerootprefix") "\"")
)
(princ)
)
Library Search Path
The library search path specifies where the program searches for files when
you do not specify a full path name, as follows:
Current directory. (This is typically determined by the Start In setting
in your shortcut icon.)
Directory that contains the current drawing file.
