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 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.
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.
 Directory that contains the current drawing file.
 Directories listed in the search path specified on the Applications tab in
OPTIONS. (See Specify Search Paths and File Locations in the User's Guide.)
 Directory that contains the AutoCAD program files.
Depending on the current environment, two or more directories may be the
same.
If a file is not in this search path, you must specify both its path name and
file name before AutoCAD can find it. For example, if you want to insert the
part5.dwg drawing into your current drawing and it is not in the library search
path, you must specify its full path name, as shown here:
