Hello,
In Data archiving (tr. SARA) there is no option to delete archive
files (either stored in file system or in content repository).
You could remove the archive files directly at content repository side,
however in this case these files will be not accessible from tr. SARA.
Storing archive files in database is not recommended. Read SAP note 71935.
There exist no standard program to remove such archived data from database table.
If really don't need these Archive files you need check with basis team.
Regards,
David
