You can set the search path to drawing support files such as text fonts, drawings, linetypes, and hatch patterns. You also can specify the location of temporary files, which is important when working in a network environment.
The Files tab of the Options dialog box is where you set the search path that is used by the program to find drawing support files such as text fonts, drawings, linetypes, and hatch patterns. The MYDOCUMENTSPREFIX system variable stores the location of the My Documents folder for the current user.
The working search path for drawing support files lists paths that are valid and exist in the current system directory structure (including system network mapping). Using these options helps improve performance when these files are loaded.
Using the Files tab of the Options dialog box, you can also specify the location of temporary files. Temporary files are created on disk, and then deleted when you exit the program. The temporary directory is set to the location that Microsoft Windows uses. If you plan to run this program from a write-protected directory (for example, if you work on a network or open files on a CD), specify a different location for your temporary files.
The temporary directory you specify must not be write-protected, and the drive containing the directory should have sufficient disk space for the temporary files. It is recommended that you manually delete the files from this directory on a regular basis to ensure sufficient space is provided for temporary files. If not enough space is available for temporary files, you may experience errors or instability in the program.
If you want to use a file that contains custom interface elements, specify it in the Customizations Files item on the Files tab of the Options dialog box. The default customization file is acad.cui.
