As aggregate storage outline files (.otl files) are changed, they may increase in size. By compacting such files, you can remove the records of deleted members and thus reduce file size.
Note: | This functionality does not apply to block storage databases. |
To compact outline files:
From Enterprise View or a custom view, locate a database.
Right-click the Outline node, and select Compact.
Optional: If you want to continue working during the compaction process, in the Compact Outline dialog box, select Compact outline in the background.
Click OK.
