There is very little administration required for the DataView addon. The attachments need to be converted from Excel into a custom index format. These indexes are stored on the file system under the "Confluence Home" shared home directory in a directory called "dataview".

Some of these index files could be reasonably large (several Megabytes). On the configuration page for the addon there is a list of currently stored indexes and their size. These index files can be removed by the Confluence Administrator if they are no longer required and can therefore save disk space.
