that your modifications do not conflict with the requirements of those
applications. Without the full path, including drive and directory, AutoCAD
LT can locate only those files that are found in the library search path.
NOTE 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.
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.
■ Directories listed in the search path specified on the Files tab in OPTIONS.
(See Specify Search Paths and File Locations in the User's Guide.)
■ Directory that contains the AutoCAD LT 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 LT 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:
Command: insert
Enter block name or [?]: /files2/olddwgs/part5
If the drawing exists in that location, AutoCAD LT prompts you to finish the
INSERT command in the usual manner.
Directory Structure
AutoCAD LT uses tree-structured directories and subdirectories. It is
recommended that you keep supplemental files (such as third-party
applications and customization files) separate from the AutoCAD LT program
