<div class="markdown level1 remarks"><p>Use this method only if you want to override the default behavior saving metadata on disk every time it changes.
Workspace storage (in the folder specified in <a class="xref" href="C1.DataEngine.Workspace.Init.html#C1_DataEngine_Workspace_Init_System_String_">Init(string)</a>) contains data (memory-mapped) files for base tables and queries and also
a file called metadata.xml containing metadata describing the structure of all base tables and queries. Metadata changes
when a new table or query is created, and it can also change when a query is executed. When DataEngine is initialized with
data already existing on disk, it is essential that metadata file contains up-to-date information. By default, it is ensured automatically by
saving the metadata file every time metadata changes. If you don't want to spend time (usually insignificant) on these autosaves,
set the <a class="xref" href="C1.DataEngine.Workspace.AutoSave.html#C1_DataEngine_Workspace_AutoSave">AutoSave</a> property to <b>false</b> and call the Save method when you are done working with the workspace.</p>
