To delete a table, choose Delete from the File menu. Select the tables to delete, then press the Delete button to delete them.
When you select Delete, a confirmation box appears, asking if you wish to permanently remove the selected table(s).
All the .DAT files that have any of the root names of the selected tables are deleted, together with their .FD, .TAG, and .K files, and their Filelist entries.
The only associated files not deleted are the .DEF files; these remain even after the use of this command.
