SPWebApplication.CellStorageDataCleanupExcludedDocTypes property
SharePoint 2013
NOTE: This API is now obsolete.
Gets or sets document types to exclude from a cell storage data cleanup timer job so that associated file fragments are not deleted.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
This property defines the set of excluded document types for which a cell storage data cleanup timer job will not delete table data. The timer job has a hard-coded list of document types that are excluded. In other words, file fragments table data that is associated with these files will not be deleted. If there are other file types which are using up SQL Server disk space in the file fragments table, then the farm server administrator can update the hard-coded list through this property.
