Cube deletion takes place in PROC OLAP and SAS OLAP
Cube Studio. If you delete cubes, that have not been updated, then
the deletion operation removes cube metadata and physical files. For
cubes that have undergone either in place or incremental update, the
deletion of old versions and generation folders occurs programmatically.
Manual file deletion is not required.
For cubes that have
undergone in-place updates, the next in-place update removes all old
generation folders.
For cubes that have
received incremental updates, deletion of metadata and physical files
takes place as part of the coalesce process.
