You can only remove a database from concatenated set, or delete a concatenated file set if you are a Concordance Desktop administrator on the Concordance Desktop server where the concatenated databases are registered. When you delete a concatenated file set, it removes the concatenation only. The databases still remain on the server and become individually accessible.
When you remove a database from an automatically concatenated set of databases, record numbering across the remaining databases will no longer be sequential. This is due to the removal of numbered records in the database that was removed, thus causing a break in the sequential order of the numbering.
1.In Concordance Desktop, open the "Primary" database of the concatenated file set.
i.The "Primary" database is the database that to which all the other databases were joined.
2.On the File menu, click Administration, then Concatenate, and then Edit concatenation.
i.The Concatenated Databases dialog box opens.
3.Click on the database you want to remove from the concatenated file set.
4.Click the Delete button.
5.Repeat steps 3 and 4 for each database you want to remove from the concatenated set.
