The Application tab (Application Preferences 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 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 folder structure (including system network
mapping). Using these options helps improve performance when these files
are loaded.
Using the Application tab (Application Preferences 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 folder is set to
the location that the operating system uses. If you plan to run this program
from a write-protected folder (for example, if you work on a network or open
files on a CD), specify a different location for your temporary files.
The temporary folder that you specify must not be write-protected, and the
drive containing the folder should have sufficient disk space for the temporary
files. It is recommended that you manually delete the files from this folder
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 Customization Files item on the Application tab (Application Preferences
dialog box). The default customization file is acadlt.cuix.
Repair, Restore, or Recover Drawing Files
If a drawing file is damaged or if your program terminates unexpectedly, you
can recover some or all of the data by using commands to find and correct
errors, or by reverting to a backup file.
