The source code analyzer writes information about files it has examined into the ``Cache
Directory`` that is listed in Wing's `About <script:about-application>`__ box, accessed
from the ``Help`` menu.

Wing does not perform well if the space available for this cache is smaller than the space
needed for a single project's source analysis information. This can be solved by
increasing the `Source Analysis > Max Cache Size
<script:show_preferences_gui#prefname="pysource.max-disk-cache-size">`__ preference.

The analysis cache may be removed in its entirety by pressing ``Clear Cache`` next to the
preference. Wing will reanalyze your code and recreate the cache as necessary.

If the same cache will be used by more than one computer, make sure the clocks of the two
computers are synchronized. The caching mechanism uses time stamps, and may become
confused if this is not done.
